Refactor channel list update event in wpa_supplicant

Browse Source 
Update hardware features for all interfaces inside the loop, don't treat
the calling wpa_s instance specially. Perform the P2P channel list
updates after the hardware features are updated. This will prevent P2P
from relying on stale information.
