[ Upstream commit f6176473a0c7472380eef72ebeb330cf9485bf0a ]

When call f2fs_acl_create_masq() failed, the caller f2fs_acl_create()
should return -EIO instead of -ENOMEM, this patch makes it consistent
with posix_acl_create() which has been fixed in commit beaf226b863a
("posix_acl: don't ignore return value of posix_acl_create_masq()").

Fixes: 83dfe53c185e ("f2fs: fix reference leaks in f2fs_acl_create")
