    ec/cluster: Update failure of fop on a brick properly

    Problem:
    In case of truncate, if writev or open fails on a brick,
    in some cases it does not mark the failure onlock->good_mask.
    This causes the update of size and version on all the bricks
    even if it has failed on one of the brick. That ultimately
    causes a data corruption.

    Solution:
    In callback of such writev and open calls, mark fop->good
    for parent too.

    Thanks Pranith Kumar K <pkarampu at redhat.com> for finding the
    root cause.
