mptcp: don't always assume copied data in mptcp_cleanup_rbuf()
Under some corner cases the MPTCP protocol can end-up invoking
mptcp_cleanup_rbuf() when no data has been copied, but such helper
assumes the opposite condition.
Explicitly drop such assumption and performs the costly call only
when strictly needed - before releasing the msk socket lock.
