RDMA/rxe: Generate a completion for unsupported/invalid opcode
commit 2f917af777011c88e977b9b9a5d00b280d3a59ce upstream.
Current rxe_requester() doesn't generate a completion when processing an
unsupported/invalid opcode. If rxe driver doesn't support a new opcode
(e.g. RDMA Atomic Write) and RDMA library supports it, an application
using the new opcode can reproduce this issue. Fix the issue by calling
"goto err;".
Fixes: 8700e3e7c485 ("Soft RoCE driver")
