Andreas Gruenbacher 6d75eb875b gfs2: Fix loop in gfs2_rbm_find ...

commit 2d29f6b96d8f80322ed2dd895bca590491c38d34 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.

Fixes: e579ed4f44 ("GFS2: Introduce rbm field bii")
