drm/virtio: fix object leak in virtio_gpu_resource_create_ioctl()

Browse source

virtio_gpu_resource_create_ioctl() calls drm_gem_object_release() on the
drm_gem_handle_create() error path instead of dropping the reference it
owns, so obj->funcs->free() never runs and the virtio_gpu_object, its
pages and sg table, the resource id and the host-side resource are
leaked.

Use drm_gem_object_put() instead.
