drm/virtio: Unlock reservations on virtio_gpu_object_shmem_init() error

Browse source 
commit fdf0ff4d12 upstream.

Unlock reservations in the error code path of virtio_gpu_object_create()
to silence debug warning splat produced by ww_mutex_destroy(&obj->lock)
when GEM is released with the held lock.
