    GFS2: gfs2_edit savemeta wasn't saving indirect eattribute blocks
    
    Normal eattribute blocks were being saved, but dinodes that had
    an eattribute pointer that leads to an indirect block
    (GFS2_METATYPE_IN) weren't being handled properly and saving
    off the sub-blocks.  This adds that capability.
