Subject: drm/vc4: Fix memory leak during gpu reset.
Git-commit: d08106796a78a4273e39e1bbdf538dc4334b2635
Patch-mainline: v5.1-rc7
References: bsc#1113722

__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.")
