[PATCH] mac80211: Call mgd_prepare_tx before deauthentication

[Sujith Manoharan <sujith@msujith.org>]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

With drivers that support multi-channel concurrency,
make sure that the correct context is in use before
sending a deauth frame. The driver could be in a different
context, in which case the frame could be dropped.
