tools: Use non-blocking read in servers

The oping and ocbr servers were using non-blocking read/writes. This
caused writes to fail on high-performance tests if the buffer got
full, instead of waiting for a slot in the buffer. The write failure
caused the server to quit. This fixes the tools by setting the I/O to
blocking write and non-blocking read.
