[PATCH AUTOSEL for 4.9 062/156] afs: Invalid op ID should abort with RXGEN_OPCODE

[alexander . levin]

From: David Howells <dhowe...@redhat.com>

[ Upstream commit 1157f153f37a8586765034470e4f00a4a6c4ce6f ]

When we are given an invalid operation ID, we should abort that with
RXGEN_OPCODE rather than RX_INVALID_OPERATION.

Also map RXGEN_OPCODE to -ENOTSUPP.
