drm/virtio: remove set but not used variable 'vgdev'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/virtio/virtgpu_ttm.c: In function 'virtio_gpu_init_mem_type':
drivers/gpu/drm/virtio/virtgpu_ttm.c:117:28: warning:
 variable 'vgdev' set but not used [-Wunused-but-set-variable]

drivers/gpu/drm/virtio/virtgpu_ttm.c: In function 'virtio_gpu_bo_swap_notify':
drivers/gpu/drm/virtio/virtgpu_ttm.c:300:28: warning:
 variable 'vgdev' set but not used [-Wunused-but-set-variable]

It is never used since introduction in dc5698e80cf7 ("Add virtio gpu driver.")
