    glfsheal: prevent background self-heals
    
    Problem:
    For a file in gfid split-brain, the parent directory ('/' during
    testing) was detected as possibly undergoing heal instead of split-brain
    in `heal-info` output. Also, it was not being displayed in `info
    split-brain` output for the same reason. The problem was that when `glfsheal`
    was run, lookup on '/' triggered a background self-heal due to which processing
    of '/' during `heal info` failed to acquire locks with errno=EAGAIN.
    
    Fix:
    Set background-self-heal-count to zero while launching glfsheal.
