Potential uninitialized variables in cfg80211

[Yizhuo Zhai]

Hi All:
net/wireless/chan.c:
Inside function cfg80211_chandef_compatible(), variable "c1_pri40",
" c2_pri40", "c1_pri80" and "c2_pri80" could be uninitialized if
chandef_primary_freqs() fails. However, they are used later in the if
statement to decide the control flow, which is potentially unsafe.

The patch is hard since we do not know the correct value to initialize them.
