Added 11d support for libertas driver using cfg80211. This is based on Holger
Shurig's initial work to add cfg80211 support libertas.
(https://patchwork.kernel.org/patch/64286/)

Please let us know, if there are any improvements comments.

Code is added to send 11d enable command to firmware while
initialisation and pass 11d specific information to firmware
when notifier handler is called by cfg80211.

In following scenarios WARN_ON() in cfg80211 code was triggered.
a) Driver unload or card removal.
b) Disconnect from infra network
c) Adhoc start/join
d) Adhoc stop
Added following fixes to avoid WARN_ON() in cfg80211 code.
a) Ensured that cfg80211_disconnected() function defined in cfg80211
code will be called only in infra mode.
b) Solved timing issue by moving cfg80211_disconnected() call inside
lbs_cfg_disconnect().
c) Updated "wdev->ssid" in driver code after Adhoc join/start
d) Removed unnecessory cfg80211_disconnected() call in lbs_remove_card.

When station management calls to ucode return
an error we could previously do nothing, but
now that almost all calls are synchronous we
can actually let the error bubble up. Use EIO

Now that the ampdu_action callback can sleep,
we can use the mutex to properly protect the
aggregation data, and return useful errors if
they should happen.

Also, add some sleep and mutex debugging so
we won't call any of the functions that now
require being able to sleep and/or the mutex
to be held in an invalid context.

Reviewed RX descriptor functions against the HAL sources. Some minor changes:

  - check size before making changes to the descriptor

  - whitespace

  - add comments about 5210 timestamps. this needs to be adressed later!

  - FIFO overrun error only available on 5210

  - rs_phyerr should not be OR'ed

  - clear the whole ath5k_rx_status structure before using, instead of
    zeroing specific fields.
