P2P: Move group removal reason to a function parameter

Browse Source 
wpa_s->removal_reason was set only when calling wpas_p2p_group_delete()
and while couple of call places did not set this, it should really be
set in each case. As such, it works better as a function parameter than
a variable in struct wpa_supplicant.
