drm/amd/display: disable CRTCs with NULL FB on their primary plane (V2)
The below commit
"drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"
introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.
This change leads to BUG hit while performing atomic commit on amd driver.
As a fix this patch ensures that we disable the CRTC's with NULL FB by returning
-EINVAL and hence triggering fall back to the old behavior and turning off the
crtc in atomic_remove_fb().
V2: Added error check for plane_state and removed sanity check for crtc.
