virtio-blk: Allow config-wce in dataplane
Dataplane now uses block layer. Protect bdrv_set_enable_write_cache with aio_context_acquire and aio_context_release, so we can enable config-wce to allow guest to modify the write cache online. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
