Consolidate the _DRM_VBLANK_NEXTONMISS handling between drm_wait_vblank
and drm_queue_vblank_event.

This is a cleanup spotted while working on other changes.

(The way it was previously handled could also theoretically result in
drm_queue_vblank_event unnecessarily bumping vblwait->request.sequence,
if the vblank counter happened to increment between the
drm_vblank_count(_and_time) calls in each function, but that's unlikely)

nouveau leaks a runtime pm ref if at least one CRTC is enabled on
unload. The ref is taken by nouveau_crtc_set_config() and held as long
as a CRTC is in use.

nv04_display_destroy() should solve this by turning off all CRTCs, but

(1) nv50_display_destroy() doesn't do the same and

(2) it's broken since commit d6bf2f37 ("drm/nouveau: run mode_config
    destructor before destroying internal display state") because the
    crtc structs are torn down by drm_mode_config_cleanup() before being
    turned off. Also, there's no locking.

Move the code to turn off all CRTCs from nv04_display_destroy() to
nouveau_display_destroy() so that it's called for both nv04 and nv50
and before drm_mode_config_cleanup(). Use drm_crtc_force_disable_all()
helper to save on code and have proper locking.

The PCI core calls pm_runtime_forbid() on device probe in pci_pm_init(),

no pm_runtime_forbid() in amdgpu_driver_unload_kms() to balance it. Add

This isn't a bug, it's just good housekeeping. When amdgpu is first
loaded with runpm=1, then unloaded and loaded again with runpm=0,
pm_runtime_forbid() will be called from amdgpu_pmops_runtime_idle() or
