Update the scan results immediately after adding the interface

After adding the newly created interface,
request the current scan results from the driver and updates
the local BSS list wpa_s->bss. This is to avoid a full scan
while processing the connect request on the newly created interface.

Bug: 202249262

Test: Ran Nearby hotspot test and confirmed that STA is able to

Test command is ./testing/mobile/devicewhisperer/tests/nearby/connections/run.sh
