4.9-stable review patch. If anyone has any objections, please let me know.

From: Tudor-Dan Ambarus <tudor.amba...@microchip.com>
[ Upstream commit 31545df391d58a3bb60e29b1192644a6f2b5a8dd ]
In crypto_authenc_esn_setkey we save pointers to the authenc keys
in a local variable of type struct crypto_authenc_keys and we don't
zeroize it after use. Fix this and don't leak pointers to the
authenc keys.
