drm: Check polling initialized before enabling in drm_helper_probe_single_connector_modes 



In function drm_helper_probe_single_connector_modes() when we enable
polling again, if it is already uninitialized, a warning is reported.
This patch fixes the warning message by checking if poll is initialized
before enabling it.
