    cluster/ec: Fix lk-owner set race in ec_unlock

    Problem:
    Rename does two locks. There is a case where when it tries to unlock it
sends
    xattrop of the directory with new version, callback of these two xattrops
can
    be picked up by two separate epoll threads. Both of them will try to set
the
    lk-owner for unlock in parallel on the same frame so one of these unlocks
will
    fail because the lk-owner doesn't match.

    Fix:
    Specify the lk-owner which will be set on inodelk frame which will not be
over
    written by any other thread/operation.
