Silent the following build warnings:

net/mac80211/mlme.c: In function ‘ieee80211_rx_mgmt_beacon’:
net/mac80211/mlme.c:1348:3: warning: ‘pwr_level_cisco’ may be used uninitialized in this function [-Wuninitialized]
net/mac80211/mlme.c:1315:6: note: ‘pwr_level_cisco’ was declared here

We seem to get this every year or so... just upgrade your compiler and
it will be smart enough to prove that it's wrong here.

I really *don't* want to shut up the compiler forcefully since it will
cause modern compilers to *not* warn if it actually *is* unused - and 0
is not a useful value - this code is tricky enough and we want compiler
help in case we need to modify it in the future.

Thank for your explanation, and please ignore the noise.

Ying
