Potential uninitialized variables in cfg80211

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.
