ath9k: Store noise immunity values across scanning

CCK/OFDM noise immunilty values are always reset to defaults
during bgscan. This could affect the link quality and
performance when the STA is associated in a noisy channel.
So do not override the learned values across the scanning.

The commit "mac80211: stop tx before doing hw config and

whenever a beacon got received with 11n htcap. This leads to
massive "Failed to stop TX DMA" logspam on embedded hw. So the

iwlagn: do not use interruptible waits

Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.

This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.

Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.

This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in  'REPLY_SCAN_ABORT_CMD'

iwlagn: unmap cmd queue's tfds as BIDI

If the driver is unloaded while there is still a host command in
flight, its tfd will be freed by iwl_tx_queue_free.
This function is called for both types of queues: Tx queues and cmd
queue. This didn't take in count the fact that in Tx queues, tfds are
mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all
TBs are mapped as BIDI.

Hence, tx_queue_free unmapped the second (and higher) TB of each tfd
in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI.
This means that if a multi TFD is in flight while we unload the
driver (which is quite unlikely but can happen), we will get the
warning below.

This patch fixes this.
