tests/osmo_io_test (io_uring): test_segmentation: Fix infinite loop in read_cb rc=0
Under linux 6.17.6-arch1-1 & liburing 2.12-1, once we finish reading from the pipe (rc=0) because the write peer was closed and data has been consumed, we end up in some sort of infinite loop in the uring due to re-adding a sqe in iofd_uring_handle_recv()->iofd_uring_submit_recv() path and immediatelly consuming a cqe from the uring, without going through the poll() loop.
The user is expected to close the fd once rc=0 is received anyway, which was not being done in this test. Doing so successfully unregisters the iofd and fixes the infinite loop.
