rsockets: Change the default QP size from 512 to 384

Simple latency/bandwidth tests using rstream showed minimal
difference in performance between using a QP sized to 384
entries versus 512.  Reduce the overhead of a default rsocket
by using 384 entries.  A user can request a larger size by
calling rsetsockopt.
