[PATCH] virtio-blk: change default config-wce to false

[Tom Yan]

This would allow `cache=` to be respected when `if=virtio` is used
(instead of `-device virtio-blk-pci`). Since `cache=writeback` is
the default, this does not cause a change in the default behavior.

Also, when `config-wce` is true, `cache.writeback` is still overriden.
