Add error handling to check NULL input in
mtk_drm_crtc_dma_dev_get function.
While display path is not configured correctly, none of crtc is
established. So the caller of mtk_drm_crtc_dma_dev_get may pass
input parameter *crtc as NULL, Which may cause coredump when
we try to get the container of NULL pointer.
Fixes: cb1d6bcca542 ("drm/mediatek: Add dma dev get function")
