    unlink_nhgrp: Remove write-only variable.
    
    Possibly one could assert that ret should always be 0 here (that is,
    that there was always an index found in the bitmask).  That should be
    true since a bitmask index is allocated before the nhgrp is inserted
    in the ctl->gr_head list in link_nhgrp.
    
    (cherry picked from commit 371c917b0b450d1944bf0ea18afdfc158af08f2e)
