dm crypt: fix error return code in crypt_ctr()
Fix to return error code -ENOMEM from the mempool_create_kmalloc_pool() error handling case instead of 0, as done elsewhere in this function. Fixes: ef43aa38063a6 ("dm crypt: add cryptographic data integrity protection (authenticated encryption)") Cc: stable@vger.kernel.org # 4.12+ Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
