mac80211: Remove unused 'struct ieee80211_rx_status' ptr

Commit 554891e6 introduced 'struct ieee80211_rx_status' in
ieee80211_rx_h_defragment but did not use it. Compiling with W=1
gives the following warning, fix it.

net/mac80211/rx.c: In function ‘ieee80211_rx_h_defragment’:
net/mac80211/rx.c:1911:30: warning: variable ‘status’ set but not used [-Wunused-but-set-variable]
