[PATCH 15/17] qemuDomainPrepareHostdev: base hostdev secret object names on backend alias



The secret object is used to pass data to the backend so it's better
fitting to base the secret object name on the SCSI host device backend
name.

Since we store the object alias in the status XML this modification is
safe in regards to existing guests.
