drm/i915/gen9: Initialize intel_state->active_crtcs during WM sanitization (v2)
intel_state->active_crtcs is usually only initialized when doing a
modeset. During our first atomic commit after boot, we're effectively
faking a modeset to sanitize the DDB/wm setup, so ensure that this field
gets initialized before use.
v2:
- Don't clobber active_crtcs if our first commit really is a modeset
(Maarten)
- Grab connection_mutex when faking a modeset during sanitization
(Maarten)
