Paolo Abeni 91b493f15d mptcp: don't always assume copied data in mptcp_cleanup_rbuf() ... commit 551844f26da2a9f76c0a698baaffa631d1178645 upstream. 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. Fixes: fd8976790a ("mptcp: be careful on MPTCP-level ack.")
