We should use the same buffer size we set up for DMA also in the hardware
descriptor. Previously we used common->rx_bufsize for setting up the DMA
mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the
descriptor itself. The problem is that skb_tailroom(skb) can give us a larger
value than the size we set up for DMA before. This allows the hardware to write
into memory locations not set up for DMA. In practice this should rarely happen
because all packets should be smaller than the maximum 802.11 packet size.

On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559
bytes length (including padding for cache alignment) but sbk_tailroom() was
2592. Just consistently use rx_bufsize for all RX DMA memory sizes.

Also use the return value of the descriptor setup function.

The current frame length used by the driver for RX frames is the SPI bus
transfer length. This length has padding bytes, which do not belong to the
WLAN frame.

As there is no other length information in the WLAN frame except the skb
length this problem caused for instance extra ESSID's to be listed at the
end of scan results (IE id 0) with zero length.

It is possible for internal scan to race against itself if the device is
not returning the scan results from first requests. What happens in this
case is the cleanup done during the abort of the first internal scan also
cleans up part of the new scan, causing it to access memory it shouldn't.

Here are details:
* First internal scan is triggered and scan command sent to device.
* After seven seconds there is no scan results so the watchdog timer
  triggers a scan abort.
* The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for
 failed scan.
* During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING
  and queue the "scan_completed" work.
** At this time, since the problem that caused the internal scan in first
   place is still present, a new internal scan is triggered.
The behavior at this point is a bit different between 2.6.34 and 2.6.35
since 2.6.35 has a lot of this synchronized. The rest of the race
description will thus be generalized.
** As part of preparing for the scan "is_internal_short_scan" is set to
true.
* At this point the completion work for fist scan is run. As part of this
  there is some locking missing around the "is_internal_short_scan"
  variable and it is set to "false".
** Now the second scan runs and it considers itself a real (not internal0
   scan and thus causes problems with wrong memory being accessed.

The fix is twofold.
* Since "is_internal_short_scan" should be protected by mutex, fix this in
  scan completion work so that changes to it can be serialized.
* Do not queue a new internal scan if one is in progress.
