Subject: [PATCH]hostap:hostap_hw.c Fix variable 'fc' set but not used

The below fixes a build wanring from GCC.

  CC [M]  drivers/net/wireless/hostap/hostap_plx.o
In file included from drivers/net/wireless/hostap/hostap_plx.c:264:0:
drivers/net/wireless/hostap/hostap_hw.c: In function 'prism2_tx_80211':
drivers/net/wireless/hostap/hostap_hw.c:1816:18: warning: variable 'fc' set but not used

Removing fc from this just introduces a new warning

drivers/net/wireless/hostap/hostap_hw.c: In function 'prism2_tx_80211':
drivers/net/wireless/hostap/hostap_hw.c:1839:3: warning: statement with no effect

So I went and removed the whole thing. Let me know if theres another solution.
