When scan and assoc (infra/ibss) commands are simultaneously
given in two terminals, association response is erroneously
served while serving the scan response.

mwifiex_cfg80211_results() is the common routine for sending
ioctl (scan, assoc etc.) results to cfg80211 stack. In above
scenario even if the common routine is called for scan ioctl
context, it also tries to send information about assoc ioctl to
cfg80211 because "priv->assoc_request/priv->ibss_join_request"
flag is on at that time.

Fix the issue by updating request variable after assoc handling
and modifying the variable check in mwifiex_cfg80211_results.

As described at http://marc.info/?l=linux-netdev&m=130428493104730&w=2
libertas frequently generates spurious tx timeouts, because the tx
queue is brought down for extended periods during scanning. The net
layer takes a look and incorrectly assumes the queue has been down for
several seconds, and generates a tx_timeout.

One way to fix this is to bump the trans_start counter while scanning
so that the network layer knows that the device is still alive, but
I think the tx_timeout handler is implemented wrongly here and not of
any real use, so I vote to remove it.

As explained at http://marc.info/?l=linux-wireless&m=130430311115755&w=2
the watchdog is primarily meant to deal with lockup on the hardware TX
path (detected by the tx queue being stopped for an extended period of
time), but this is unlikely to happen with libertas. In this case, the tx
queue is stopped only while waiting for lbs_thread to send the queued frame
to the driver, and lbs_thread wakes up the queue immediately after, even
if the frame could not be sent correctly.

So, the only hardware-related possibility that this catches is if
hw_host_to_card hangs - this is something I have never seen. And if it
were to happen, nothing done by lbs_tx_timeout would actually wake up
lbs_thread any quicker than otherwise.

Removing this oddly-behaving spuriously-firing tx_timeout handler should
fix an occasional kernel crash during resume

When operating as AP, the TX queues are not stopped when we start
recovery. mac80211 is notified only after the fact. When there is
pending TX, it will be queued even after the FW is down. This leads to
situations where the TX queues are stopped (because of the TX-watermark
mechanism), and are never woken up when we return from recovery.

Fix this by explicitly stopping the TX queues when before initiating
recovery.
