    cluster/afr: Fix heal-info slow response while IO is in progress
    
    Now heal-info does an open() on the file being examined so that
    the client at some point sees open-fd count being > 1 and releases
    the eager-lock so that heal-info doesn't remain blocked forever
    until IO completes.
