[libvirt] [PATCH 02/13] qemu: alias: Allow passing alias of parent when generating PR manager alias

[Peter Krempa]

For use with blockdev the PR manager will be bound to a virStorageSource
rather than a virDomainDiskDef, so we will need to use the correct
alias.

Allow passing a string rather than the whole disk.
