mac80211: Remove unused assignment statements 



The assignment of these three local variables in the file will not
be used in the corresponding functions, so they should be deleted.

The clang_analyzer complains as follows:

net/mac80211/wpa.c:689:2 warning:
net/mac80211/wpa.c:883:2 warning:
net/mac80211/wpa.c:452:2 warning:

Value stored to 'hdr' is never read
