CVE-2024-41079

In the Linux kernel, the following vulnerability has been resolved:

nvmet: always initialize cqe.result

The spec doesn't mandate that the first two double words (aka results)

for the command queue entry need to be set to 0 when they are not

used (not specified). Though, the target implemention returns 0 for TCP

and FC but not for RDMA.

Let's make RDMA behave the same and thus explicitly initializing the

result field. This prevents leaking any data from the stack.
