Disk targets are generated in virVMXParseConfig() with
virVMXGenerateDiskTarget(). It works on combination of
controller, fix offset, unit and prefix. While SCSI and SATA have
same prefix "sd", function virVMXGenerateDiskTarget() could
returned in some cases same targets.
In this patch, after loaded SCSI and SATA disks to the def,
indexes are regenerated, now simply from position of the disk in
array of disks (def). With this, required uniqueness is
guaranteed.
Because assigned addresses of disks are generated from their
indexes, for every changed SATA disk is called
virDomainDiskDefAssignAddress() with the updated value.
The corresponding tests have been modified to match the index
changes.

Since previous version in mailing list was complicated for trying to
preserve the indexes of SCSI and previous tests, this one going to
straightforward, although it changes all (SCSI and SATA) indexes. It's
not a bug, since we cannot guarantee the same naming inside the guest
anyway.
