drm/amd/display: don't call dc_interrupt_set() for disabled crtcs

[ Upstream commit 6404c18c7e8ea0f193586bd9615049b2217b2d7a ]

As made mention of in commit ef0d1a47bd2b ("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().
