[ Upstream commit 66eb02d839e8495ae6b612e2d09ff599374b80e2 ]
Initialize 'n' to 2 in order to take into account also the first
packet in the estimation of max_subframe limit for a given A-MSDU
since frag_tail pointer is NULL when ieee80211_amsdu_aggregate
routine analyzes the second frame.
Fixes: 6e0456b54545 ("mac80211: add A-MSDU tx support")
