bgscan_learn: Fix initial interval

Browse source 
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.
