p2p: Fix Device Address updates from Probe Requests

Browse Source 
p2p_peer_update_existing may be called with a scan_bss struct built from
a Probe Request frame so it can't access bss->p2p_probe_resp_info even
if peer->bss was built from a Probe Response.  Check the source frame
type of the scan_bss struct before updating the Device Address.

This fixes one timing issue that would make the autotest fail often.
