Subject: afs: Invalid op ID should abort with RXGEN_OPCODE
From: David Howells <dhowells@xxxxxxxxxx>
[ 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.
