mac80211: do not convert to A-MSDU if frag/subframe limited

Browse Source 
[ Upstream commit 1eb5079036 ]

Do not start to aggregate packets in a A-MSDU frame (converting the
first subframe to A-MSDU, adding the header) if max_tx_fragments or
max_amsdu_subframes limits are already exceeded by it. In particular,
this happens when drivers set the limit to 1 to avoid A-MSDUs at all.
