[PATCH 4.4 022/241] crypto: gcm - Fix error return code in crypto_gcm_create_common()

[Greg Kroah-Hartman]

From: Wei Yongjun <weiyongj...@huawei.com>

commit 9b40f79c08e81234d759f188b233980d7e81df6c upstream.

Fix to return error code -EINVAL from the invalid alg ivsize error
handling case instead of 0, as done elsewhere in this function.
