As made mention of in commit 4ea7fc09539b ("drm/amd/display: Do not
program interrupt status on disabled crtc"), we shouldn't program
disabled crtcs. So, filter out disabled crtcs in dm_set_vupdate_irq()
and dm_set_vblank().
Fixes: 589d2739332d ("drm/amd/display: Use crtc enable/disable_vblank hooks")
Fixes: d2574c33bb71 ("drm/amd/display: In VRR mode, do DRM core vblank handling at end of vblank. (v2)")
