Subject: [PATCH 1/5 v2]wireless:hostap_main.c warning: variable 'iface' set but not used

This is a resend from version one due to trying a different approach
than the original(probably important to leave netdev_priv() in).

In any case have a look, if there's another approach let me know
and ill test it out. The below patch fixes a warning im seeing
when compiling with gcc 4.6.0

CC [M]  drivers/net/wireless/hostap/hostap_main.o
drivers/net/wireless/hostap/hostap_main.c: In function 'hostap_set_multicast_list_queue':
drivers/net/wireless/hostap/hostap_main.c:744:27: warning: variable 'iface' set but not used
