wpa_supplicant: Start bgscan on COMPLETED, not ASSOCIATED

Browse Source 
Move the code snippet to switch on bgscan over to wpa_supplicant.c
from event.c, so that it can be activated on wpa_supplicant_set_state().
Also create a centralized place to switch off bgscan. bgscan is now
turned on in COMPLETED, not ASSOCIATED.
