[PATCH] virtio-blk: advertise F_WCE (F_FLUSH) if F_CONFIG_WCE is advertised

Virtio spec 1.1 (and earlier), 5.2.5.2 Driver Requirements: Device Initialization: "Devices SHOULD always offer VIRTIO_BLK_F_FLUSH, and MUST offer it if they offer VIRTIO_BLK_F_CONFIG_WCE" Currently F_CONFIG_WCE and F_WCE are not connected to each other. Qemu will advertise F_CONFIG_WCE if
