[PATCH 1/2] drm/vc4: Fix memory leak during gpu reset.

[Maarten Lankhorst]

__drm_atomic_helper_crtc_destroy_state does not free memory, it only
cleans it up. Fix this by calling the functions own destroy function.

Fixes: 6d6e50039187 ("drm/vc4: Allocate the right amount of space for boot-time CRTC state.")
