P2P: Be more careful with wpa_config_update_psk() call

Browse Source 
Commit bb4d4deb4b introduced a code path
that could potentially end up calling wpa_config_update_psk() with NULL
passphrase. While that may not happen in practice, it is better to make
sure it doesn't happen since that function will dereference the
passphrase pointer unconditionally.
