blockdev: flip default cache mode from writethrough to writeback
Now all major device models (IDE, SCSI, virtio) can choose between
writethrough and writeback at run-time, and virtio will even revert
to writethrough if the guest is not capable of sending flushes. So
we can change the default to writeback at last.
Tested, for lack of a better idea, with a breakpoint on bdrv_open
and all cache choices one by one.
