[PATCH 5/5] drm/client: Remove unused drm_client_modeset_check

[linux@treblig.org]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

drm_client_modeset_check() was explicitly added in 2020 by
commit 64593f2a6fc9 ("drm/client: Add drm_client_modeset_check()")
but has never been used.

Remove it.
