Linux 4.7 compat: fix zpl_get_acl returns invalid acl pointer
Starting from Linux 4.7, get_acl will set acl cache pointer to temporary
sentinel value before calling i_op->get_acl. Therefore we can't compare
against ACL_NOT_CACHED and return.
Since from Linux 3.14, get_acl already check the cache for us, so we
disable this in zpl_get_acl.
Linux 4.7 also does set_cached_acl for us so we disable it in zpl_get_acl.
