drm/irq: Remove negative CRTC index special-case
The drm_send_vblank_event() function treats negative CRTC indices as meaning that a driver doesn't have proper VBLANK handling. This is the only place where DRM needs negative CRTC indices, so in order to enable subsequent cleanup, remove this special case and replace it by the more obvious check for whether or not VBLANK support was initialized.
