Abhijith Das 6a98c333ed 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.
