[PATCH 2/3] gpu: drm: Remove unnecessary parameter from drm_ht_remove_item()

[Masaru Nomura]

removed drm_open_hash from drm_ht_remove_item() as the parameter is
not used within the function.

Signed-off-by: Masaru Nomura <massa.nomura@xxxxxxxxx>

Please review this patch carefully. The reason the parameter is passed
might be some historical one or clarity of which drm_open_hash
we remove an item from.
