[Cluster-devel] [PATCH 10/14] libgfs2: Const-ify the 'ri' argument to gfs2_rindex_out

[Andrew Price <anprice@redhat.com>]

This function shouldn't modify its ri argument and the const helps when we want
to pass it the return value of one of the newly-const lgfs2_rgrp_{index,rgrp}
functions (the rgrp arg to gfs2_rgrp_out is already const so no change needed).
