gfs2: Pass resource group to rgblk_free

Sfoglia il codice sorgente 
Function rgblk_free can only deal with one resource group at a time, so
pass that resource group is as a parameter.  Several of the callers
already have the resource group at hand, so we only need additional
lookup code in a few places.
