drm/nouveau: Fix drm poll_helper handling
Commit cae9ff036eea effectively disabled the drm poll_helper by checking
the wrong flag to see if the driver should enable the poll or not:
mode_config.poll_enabled is only set to true by poll_init and it is not
indicating if the poll is enabled or not.
nouveau_display_create() will initialize the poll and going to disable it
right away. After poll_init() the mode_config.poll_enabled will be true,
but the poll itself is disabled.
To avoid the race caused by calling the poll_enable() from different paths,
this patch will enable the poll from one place, in the
nouveau_display_hpd_work().
In case the pm_runtime is disabled we will enable the poll in
nouveau_drm_load() once.
Fixes: cae9ff036eea ("drm/nouveau: Don't enabling polling twice on runtime resume")
