[PATCH 1/2] librdmacm/rstream: Reduce default transfer count

[sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org]

From: Sean Hefty <sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

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.
