Usually, filesystem will use a function named as fs_init_acl function that belong
to acl.c and this function is externed in acl.h by using CONFIG_FS_POSIX_ACL.
If filesystem disable this switch, we should not call xfs_set_acl also not call
posix_acl_create/posix_acl_release because it is useless(We have do umask
strip in vfs).
