Fix a long-standing bug/misunderstanding between the
driver and the firmware.  The size of the interrupt
queue must be set to the number of rx slots (big + small),
and it should never have been a tunable.
Setting it too small results in chaos.

When, for some reason, the rt2x00pci module fails to allocate DMA memory for
the queues, it tries to undo the complete initialization of the PCI device,
including freeing of the irq. This results in the following error in dmesg, as
the irq hadn't been requested yet:

[  78.123456] Trying to free already-free IRQ 17

Fix this by implementing proper error handling code, instead of just using the
full uninitialization function.

During initialization the initialize() callback function
in rt2x00pci and rt2x00usb will cleanup the mess they made.

rt2x00lib shouldn't call uninitialize because the callback function already
cleaned up _and_ the DEVICE_INITIALIZED isn't set which causes the
rt2x00lib_uninitialize() to halt directly anyway. All that is required
to be cleaned up by rt2x00lib is the queue, and that can be done by
calling rt2x00queue_uninitialize() directly.

rt2x00pci allocates DMA for descriptor and data,
rt61pci doesn't use this for the beacon, but it can
use the descriptor part as temporary buffer instead
of using pskb_expand_head().
Using this temporary buffer is obviously much better
then reallocating the skb buffer...

At the same time we can set the data length for the
beacon queue at 0, to make sure no DMA is allocated for
data (but just for the descriptor).

A file in the net/mac80211 directory uses "int" for flags.  This can cause

If session is NULL, it is not possible to access its name field.  So I
have split apart the printing of the error message to drop the
printing of the name field in this case.

The macro PRINTK actually only evaluates its arguments starting with
the third one if the bitwise conjunction of the first two is non-zero.
Normally, this conjunction would only be non-zero if debugging mode
were turned on, but when session is NULL, the first argument in both
the old and new code is -1, and thus the bitwise conjunction is true.
Perhaps a different strategy is desired, such as using tunnel->debug,
which session->debug is initialized to, but tunnel can also be NULL,
so this does not completely solve the problem.
