[PATCH 2/2] drm: mediatek: mtk_drm_crtc: Use kmalloc in mtk_drm_crtc_duplicate_state

[AngeloGioacchino Del Regno]

Optimize mtk_drm_crtc_duplicate_state() by switching from kzalloc() to
kmalloc(): the only variable of this struct that gets checked in other
functions is `pending_config`, but if that's set to false, then all of
the remaining variables will only ever be set, but not read - so, also
set `pending_config` to false.
This saves us some small overhead.
