This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

====================
Here's another round of updates for -next:
* big A-MSDU RX performance improvement (avoid linearize of paged RX)
* rfkill changes: cleanups, documentation, platform properties
* basic PBSS support in cfg80211
* MU-MIMO action frame processing support
* BlockAck reordering & duplicate detection offload support
* various cleanups & little fixes

Since the PNs of all the tx keys are now tracked in the public
part of the key struct (with atomic counter), we no longer
need these functions.
dvm and vt665{5,6} are currently the only users of these functions,
so update them accordingly.

Presently the TX buffer stops while filling the buffer and urb.
However, this does not make use of the available buffer
space, it also lags the speed of the TX troughtput.
Only stop the queue when the buffer becomes full. The
URB complete will start the queue again when a
buffer and URB is available.

Information for packet type is in ieee80211_tx_info
band IEEE80211_BAND_5GHZ for PK_TYPE_11A.
IEEE80211_TX_RC_USE_CTS_PROTECT via tx_rate flags selects PK_TYPE_11GB
This ensures that the packet is always the right type.

This patch focuses on fixing the following warning generated

This patch merges an assignment with an immediately following return of
the assigned variable. The following Coccinelle semantic patch was used
to make this transformation:
@@
expression ret;
identifier f;
@@
-ret =
+return
f(...);
-return ret;
A variable that became unused due to this transformation was also removed.
