Subject: [PATCH net 0/6] mptcp: fixes for v6.2

Patch 1 clears resources earlier if there is no more reasons to keep
MPTCP sockets alive.

Patches 2 and 3 fix some locking issues visible in some rare corner
cases: the linked issues should be quite hard to reproduce.

Patch 4 makes sure subflows are correctly cleaned after the end of a
connection.

Patch 5 and 6 improve the selftests stability when running in a slow
environment by transfering data for a longer period on one hand and by
stopping the tests when all expected events have been observed on the
other hand.

All these patches fix issues introduced before v6.2.
