wifi: cfg80211: sme: init n_channels before channels[] access

Browse source

With the __counted_by annocation in cfg80211_scan_request struct,
the "n_channels" struct member must be set before accessing the
"channels" array. Failing to do so will trigger a runtime warning
when enabling CONFIG_UBSAN_BOUNDS and CONFIG_FORTIFY_SOURCE.
