[PATCH V2 05/16] src/locktest.c: Clean up client command passing

[ira.weiny@intel.com]

From: Ira Weiny <ira.weiny@intel.com>

The client was using the test index rather than the values being passed
to it for a command.  While this technically worked it is cleaner to
fully initialize the command message and use the values in that message.
