qemu: domain: aggregate setup of disk drive options for -drive

When using blockdev the approach to base aliases will change. Add a
helper function that will aggregate all code which needs to be called
with the disk alias for the -drive to setup internal data.

qemuDomainSecretDiskPrepare wrapper is no longer necessary as the
contents were moved to a function which is designed to use the old
aliases.
