selftests/net: don't tests batched TCP io_uring zc

Browse Source 
It doesn't make sense batch submitting io_uring requests to a single TCP
socket without linking or some other kind of ordering. Moreover, it
causes spurious -EINTR fails due to interaction with task_work. Disable
it for now and keep queue depth=1.
