How do you start wpa_supplicant in a case where this happens? I.e., what
kind of interfaces are initialized and in which order on the command
line? wpas_p2p_deinit_global() is now supposed to be called when the
interface that was used to initiate the global P2P context is removed.

And that call I mention above should happen from
wpa_supplicant_remove_iface().. If you are seeing a case where this does
not happen that could indicate that something else is broken and that
should be fixed instead of adding this extra call into
wpa_supplicant_deinit().
