bgscan_learn: scan all freq only if there are no candidates (INTERNAL)
change to patch 19958a54733009e7ef07dc10d98c8b04fa94b882
The original fix to bgscan_learn performs a scan on
all frequencies if bss candidates were not seen on other
channels.
This patch changes it so that if a candidate bss was
seen on the channel of the current AP do not scan
all frequencies.
