We could have also solved this by using a three-state enum with the
default state being 0 rather than -1:

enum {
   VIR_DOMAIN_DISK_RAWIO_DEFAULT = 0,
   VIR_DOMAIN_DISK_RAWIO_NO = 1,
   VIR_DOMAIN_DISK_RAWIO_YES = 2,
}

which we have done for other setups, as that avoids the need for a
separate bool value.  But I'm not too worried about what you did to
bother changing things.
