wifi: fix find_freq() implementation

As we iterate over "self->num_freqs", we must not modify "freqs",
otherwise, the second and subsequenty frequencies in self->freqs[i]
cannot match.

Fixes: dd8c546ff052 ('2007-12-27  Dan Williams  <dcbw@redhat.com>')
Fixes: ba8527ca58bd ('wifi: preliminary nl80211 patch')
