Debug print scan results matching the currently selected network

Browse source 
This provides more details on BSS selection process in the debug log.
Previously, the BSSs that were not either the current or the selected
one were not necessarily printed at all. Now all BSSs that match the
currently selected network are listed with their frequency and signal
strength details.
