9921d5013a selftests/net: don't tests batched TCP io_uring zc 
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.

d8b6171bd5 selftests/io_uring: test zerocopy send 
Add selftests for io_uring zerocopy sends and io_uring's notification
infrastructure. It's largely influenced by msg_zerocopy and uses it on
the receive side.
