From: John Harrison <John.C.Harrison@xxxxxxxxx>
For some reason, the i915_add_request() call in
i915_gem_execbuffer_retire_commands() was explicitly having its return code
ignored. The _retire_commands() function itself was 'void'. Given that
_add_request() can fail without dispatching the batch buffer, this seems odd.
Also shrunk the parameter list to a single structure as everything it requires
is available in the execbuff_params object.
