GFS2: Fix fstrim boundary conditions
This patch correctly distinguishes two boundary conditions:
1. When the given range is entire within the unaccounted space between
two rgrps, and
2. The range begins beyond the end of the filesystem
Also fix the unit of the returned value r.len (total trimming) to be in bytes
instead of the (incorrect) 512 byte blocks
With this patch, GFS2 passes multiple iterations of all the relevant xfstests
(251, 260, 288) with different fs block sizes.
