qemu: Use the hostdev alias in qemuDomainAttachHostSCSIDevice error path

https://bugzilla.redhat.com/show_bug.cgi?id=1289391

Rather than pass the whole drive string (which contained the alias),
pass only the alias for the qemuMonitorDriveDel call in the error
path when adding a host device in the monitor fails.
