P2P: Fix p2p_connect join scan handler in error cases

Browse source 
wpa_drv_scan() may fail for the initial p2p_connect join scan request,
e.g., if the driver happened to be scanning at the time the new
operation was initialized. Previously, a special scan result handler was
registered regardless of whether the new scan was started. This could
result in partial scan results (e.g., from p2p_find social scan) from
being used as full results for join (or now more importantly for
p2p_connect auto) purposes. Fix this by registering the new scan result
handler only if wpa_drv_scan() returns success.
