It is now possible to create command complete event without specific
reply data by passing NULL as reply with len 0. Check pointer before
calling memcpy to avoid undefined behaviour.

All of the places that need to call mgmt_pending_remove already have a
pointer to the pending command, so searching for the command in the list
doesn't make sense. The added benefit is that many places that

mgmt_pending_remove now.

The module parameter ieee80211_disable_40mhz_24ghz
was meant to allow disabling 40 MHz operation in
the 2.4 GHz band by default. However, it is buggy
as implemented because while it advertises to the
AP that the device doesn't support 40 MHz, it will
itself still use 40 MHz configurations.

To fix this, clear the 40 MHz bits from the sband
completely instead of overriding where used.

Correct channel setting function must be used for AR2317.
When I tested ahb patch on bullet2 all seemed to work fine,
but it couldn't connect another host (using ibss for example).
During an analysis I observed that it's transmitting on another
channel. I looked into madwifi code and understood that
the problem is in channel setting function. So atheros RF2317 not
fully handled in the current ath5k version and must be patched.
