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

------------------

From: Sabrina Dubroca <sd@queasysnail.net>

commit 106840c41096a01079d3a2025225029c13713802 upstream.

generic_gcmaes_decrypt needs to use generic_gcmaes_ctx, not
aesni_rfc4106_gcm_ctx. This is actually harmless because the fields in
struct generic_gcmaes_ctx share the layout of the same fields in
aesni_rfc4106_gcm_ctx.

Fixes: cce2ea8d90fe ("crypto: aesni - add generic gcm(aes)")
