Why do we need this patch? Currently qemuDomainDetermineDiskChain still
gets called on all disks where it makes sense. Exceptions are:
1) empty drives (this is also redundant, since
qemuDomainDetermineDiskChain will check it again).

2) disk source formats that don't support backing chains, where we just
check that the file exists.

This patch would make us call that on those too.

NACK,

Peter
