[PATCH][drm-next] drm/vkms: remove unused pointer vkms_obj

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Pointer vkms_obj is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
variable ‘vkms_obj’ set but not used [-Wunused-but-set-variable]
