librdmacm/rstream: Adjust transfer counts
A customer has reported that 100 transfers for large sizes
is insufficient to achieve the top bandwidth over a high
latency link. Contrary, 100,000 transfers is too high for
small latency ping-pong over a slow connection.

librdmacm/rsocket: Fix resetting O_NONBLOCK after calling shutdown
Shutdown switches an rsocket from nonblocking to blocking to
ensure that all data has been sent. After completing all
transfers, it should switch back to nonblocking; this handles
partial shutdown situations, where only half the connection
is shut down. However, the code uses the value of '1' to
set the nonblocking flag, rather than O_NONBLOCK. Fix this.

librdmacm/rstream: Reduce default transfer count
1 million ping-pong transfers takes over 3 seconds to
complete, and I'm impatient. Reduce the default number of
transfers for small messsages to speed up running
performance tests, especially when running over slower
connections, like TCP sockets or over a WAN.
