[libvirt] [PATCH RFC 10/40] qemu: Replace use of virDomainDiskFindByBusAndDst with virDomainDiskByTarget

[Peter Krempa]

In both replaced cases we have other code that verifies that the bus
can't be changed or that the target is unique, so limiting the search to
disks with same bus makes no sense.
