    gfs2_convert: interrupted rgrp conversion does not allow re-converts
    
    Resolves bz 548585. Zero out gfs1 rgrp's rg_freemeta field after
    adding it to gfs2 rgrp's free blocks. This should only be done once.
    If convert fails or is interrupted and is restarted later on, adding
     a non-zero rg_freemeta to the free blocks again throws off the
    numbers and breaks allocation.

    Resolves: rhbz#548585
