overlay/071: Don't compare inode numbers in lower overlay and nested overlay

1) If underlying filesystem is ext4, the lower overlay inodes do not
   have the MSB set (e.g. file ino 8590721028 = 0x2000C0004) because
   ext4 has a known inode number limit of 32bit (see ovl_can_decode_fh).
2) With nested xino feature, the nested overlay inodes have the MSB set
   (e.g. file ino 9223372045445496836  = 0x80000002000C0004).
It is expected different inode numbers which casue the failure of
overlay/071, so fix this failure by removing the unneeded comparision.
