nilfs2: fix gcc warning at nilfs_checkpoint_is_mounted()

Fix the following build warning:

 fs/nilfs2/super.c: In function 'nilfs_checkpoint_is_mounted':
 fs/nilfs2/super.c:1023:10: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
   if (cno < 0 || cno > nilfs->ns_cno)
           ^

This warning indicates that the comparision "cno < 0" is useless because
variable "cno" has an unsigned integer type "__u64".
