mptcp: factor out mptcp_connect()
The current MPTCP connect implementation duplicates a bit of inet
code and does not use nor provide a struct proto->connect callback,
which in turn will not fit the upcoming fastopen implementation.
Refactor such implementation to use the common helper, moving the
MPTCP-specific bits into mptcp_connect(). Additionally, avoid an
indirect call to the subflow connect callback.
Note that the fastopen call-path invokes mptcp_connect() while already
holding the subflow socket lock. Explicitly keep track of such path
via a new MPTCP-level flag and handle the locking accordingly.
Additionally, track the connect flags in a new msk field to allow
propagating them to the subflow inet_stream_connect call.
Fixes: d98a82a6afc7 ("mptcp: handle defer connect in mptcp_sendmsg")
