common/attr: adbjust acl_max of f2fs

f2fs has set inline_xattr as a default option, and introduced a new
option named 'noinline_xattr' for disabling default inline_xattr
option.  So in _acl_get_max we need to check 'noinline_xattr' string
in fs option, otherwise we may select the wrong max acl number since
we always found the string 'inline_xattr' in fs option.

Additionally, f2fs has changed disk layout of xattr block a bit, so
will contain one more entry in both inline and noinline xattr inode,
this patch will modify the max acl number to adjust it.
