[PATCH] nilfs2: remove two dead '#if 0' blocks

[Breno Rodrigues Alves]

Remove two blocks of code that have been disabled with '#if 0' since
the initial nilfs2 import:

  - inode.c: the code that would have read i_file_acl and i_dir_acl
    from the on-disk inode.  nilfs2 has never implemented ACLs, and
    the i_file_acl/i_dir_acl fields do not exist in struct
    nilfs_inode_info, so this block has never been compiled.

  - super.c: the classic ext2 "maximal mount count reached" check.
    nilfs2 reads and rewrites s_max_mnt_count for on-disk
    compatibility, but the check itself was never enabled.  Removing
    the disabled branch does not change the on-disk format or the
    behaviour of the driver.

No functional changes.
