The following patch maps it correctly, but it only works if the device
is already 'primary', which kind of defeats the purpose... qemu-dm must
be trying to open the device before the drbd script switches the local
node to 'primary'. Might it still be a useful addition to qemu-dm
though? (eg it would work in a multiple-primary setup).
