drm/amd/display: Fix misuse of plane state destroy helper

Browse source

drm_plane_state is subclassed by dm_plane_state, so atomic driver should
use __drm_atomic_helper_plane_destroy_state() to destroy a state.
drm_atomic_helper_plane_destroy_state() frees drm_plane_state which is
allocated inside dm_plane_state, this is problematic.
