drm/vc4: Set ->legacy_cursor_update to false when doing non-async updates

Browse source

commit fcc86cb45d upstream.

drm_atomic_helper_setup_commit() auto-completes commit->flip_done when
state->legacy_cursor_update is true, but we know for sure that we want
a sync update when we call drm_atomic_helper_setup_commit() from
vc4_atomic_commit().

Explicitly set state->legacy_cursor_update to false to prevent this
auto-completion.

Fixes: 184d3cf4f7 ("drm/vc4: Use wait_for_flip_done() instead of wait_for_vblanks()")
