Andreas Gruenbacher 6ef56c9ad7 gfs2: Fix loop in gfs2_rbm_find ...

commit 2d29f6b96d upstream.

Fix the resource group wrap-around logic in gfs2_rbm_find that commit
e579ed4f44 broke.  The bug can lead to unnecessary repeated scanning of the
same bitmaps; there is a risk that future changes will turn this into an
endless loop.
