brcmsmac uses info->control.sta while doing ampdu aggregation. This patch
changes the usage of the structure info->control.sta, as it is going to be
removed soon from struct ieee80211_tx_info. This patch is a pre-requisit in
order to add transmission power control (TPC) to the mac80211 subsystem.

sta pointer is not used in brcms_c_sendampdu(), sta removed. thx to A.v.Spriel

Now it probably results in a compiler warning. Declaration can go as well.
