[PATCH] wpa_supplicant: Store absolute path to P2P config file

[Andrei Otcheretianski]

When wpa_supplicant is daemonized, relative paths are not valid anymore.
If the P2P device is toggled (disabled/enabled) when wpa_supplicant runs
with -B option, the configuration isn't found and P2P device interface
can't be re-added.
