mptcp: fix subflow bitfield misuse
The subflow status bitfield is protected by the subflow socket lock,
with one notable exception: the `close_event_done` bit is actually under
the msk socket lock protection.
As reported by Clashiko [1], flipping the latter bit may corrupt other
entries in the same bitfield.
Move the `close_event_done` outside the bitfield, in a 32bit hole.
