[PATCH perftest] perftest: make inline send on ocrdma work better

[Jarod Wilson <jarod-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

The ocrdma driver supports a maximum inline send size of 224, while the
current code sets this size to 236. Add an ocrdma-specific check when
setting max inline size to eliminate the need to always pass -I 224 when
running ib_send_lat on ocrdma hardware.
