From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
commit d08106796a78a4273e39e1bbdf538dc4334b2635 upstream.
__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.")
