mptcp: reset fallback status gracefully at disconnect() time
mptcp_disconnect() clears the fallback bit unconditionally, without
touching the associated flags.
The bit clear is safe, as no fallback operation can race with that --
all subflow are already in TCP_CLOSE status thanks to the previous
FASTCLOSE -- but we need to consistently reset all the fallback related
status.
Also acquire the relevant lock, to avoid fouling static analyzers.
