This solves issues/91 for me at least. Targeting upstream -net.
As such, patches based on the "bottom" of current export branch,
so that should apply cleanly on current -net.

Note that rebasing on top of patch 2 "mptcp: refactor shutdown and close",
we must change the value of the macro MPTCP_WORKER_RUNNING (5 -> 6)

The problem fixed by patch 2/2 already exist in the curren export/net 
branches - is quite rare, but is more visible after patch 1/2.

This iteration addresses the comment from Mat on patch 2/2

  mptcp: fix fallback for MP_JOIN subflows
