    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
