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

Browse Source 
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.
