-Subject: mptcp: continue marking the first subflow as UNCONNECTED

-
-After the 'Fixes' commit mentioned below, which is a partial backport,
-the MPTCP worker was no longer marking the first subflow as "UNCONNECTED"
-when the socket was transitioning to TCP_CLOSE state.
-
-As a result, in v6.1, it was no longer possible to reconnect to the just
-disconnected socket. Continue to do that like before, only for the first
-subflow.
-
-A few refactoring have been done around the 'msk->subflow' in later
-versions, and it looks like this is not needed to do that there, but
-still needed in v6.1. Without that, the 'disconnect' tests from the
-mptcp_connect.sh selftest fail: they repeat the transfer 3 times by
-reconnecting to the server each time.

-Fixes: 7857e35ef10e ("mptcp: get rid of msk->subflow")
