P2P: Always use global p2p_long_listen

Browse source 
The p2p_long_listen value was set on the control wpa_s struct while in a
lot of cases it operated on the p2p struct. Explicitly use the global
p2p_init_wpa_s struct in cases where we might not be operating on it
already.

Without this, simply starting a p2p_listen operation (e.g., using
wpa_cli) will not work properly. As the p2p_long_listen is set on the
controlling interface and wpas_p2p_cancel_remain_on_channel_cb() uses
p2p_init_wpa_s, it would not actually work. This results in
wpa_supplicant stopping listening after the maximum remain-on-channel
time passes when using a separate P2P Device interface.
