P2P: Handle INTERFACE_DISABLED event on a P2P GO interface

An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.

The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.
