uss/gluster: generate gfid for snapshot files from snapname and gfid
If 'a' and 'b' are hardlinks, we need to generate a virtual
gfid for these files so that the inode number for 'a' and 'b'
are same.
Generate gfid as below:
gfid_of_a = MD5(snapname + back_end_gfid(a))
if '/dir1/a' and '/dir2/b' are hardlinks, then inode number should be
same for
all below files:
/mnt/.snaps/snap1/dir1/a
/mnt/.snaps/snap1/dir2/b
/mnt/dir1/.snaps/snap1/a
/mnt/dir2/.snaps/snap1/b
