nl80211: Allow association to change channels during reassociation
nl80211_associate() was rejecting (re)association attempts with EBUSY in some cases where we are currently associated with an AP that uses different channel from the destination AP. Fix this by passing the current wdev to rdev_fixed_channel() in the same way that was already done for join-IBSS and connect commands. This allows the fixedchan check to skipped for the current wdev and allows the reassociation to proceed. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W.
