    mac80211: make tx() operation return void · 7bb45683

    The return value of the tx operation is commonly
    misused by drivers, leading to errors. All drivers
    will drop frames if they fail to TX the frame, and
    they must also properly manage the queues (if they
    didn't, mac80211 would already warn).
    
    Removing the ability for drivers to return a BUSY
    value also allows significant cleanups of the TX
    TX handling code in mac80211.
    
    Note that this also fixes a bug in ath9k_htc, the
    old "return -1" there was wrong.
