drm/msm: wait_for_completion_timeout return is never negative

wait_for_completion_timeout returns >= 0 but never
negative  - so the error check should be against equality
to 0 not <= 0.

drm/msm: fixup wait_for_completion_timeout handling

wait_for_completion_timeout return >= 0 but never negative so the check
logic looks inconsistent. Further the return value of

x call sites as drm_dp_i2c_do_msg()/drm_dp_dpcd_access() check for < 0
thus timeout was being treated as success case.

<snip> drivers/gpu/drm/drm_dp_helper.c:drm_dp_i2c_do_msg()
                mutex_lock(&aux->hw_mutex);
                ret = aux->transfer(aux, msg);

<snip>
logic in edp_aux_transfer() seems incorrect as it could return 0 (timeout)
but checks of <= 0 to indicate error so the return probably should be
