bgscan_learn: fix initial interval
In case the initial signal level of the associated BSS
was above the given threshold , bgscan_learn module would
begin using the short_interval but never switch to the
long_interval as there would be no signal change event.
Make the init code poll for the current signal level and
set scan_interval accordingly.
This logic exists in bgscan_simple but was missing in
bgscan_learn.
