Paolo Abeni 7b8e734d7b mptcp: ensure subflow is unhashed before cleaning the backlog
commit 3fffa15bfe upstream.

While tacking care of the mptcp-level listener I unintentionally
moved the subflow level unhash after the subflow listener backlog
cleanup.

That could cause some nasty race and makes the code harder to read.

Address the issue restoring the proper order of operations.
