SCSI identifier checks should check more than just port 0

[holysoles]

I have a virtual machine that bypassed the SCSI identifier checks that has the QEMU device on port 1 rather than port 0. Port 0 exists, but has no Target ID entries.

Regkey path: HKLM\HARDWARE\DEVICEMAP\Scsi\Scsi Port 1\Scsi Bus 0\Target Id 0\Logical Unit Id 0

I suggest we check ports 0-2 like is done in this blog post to have better coverage of possible detection methods given this is publicly documented. This should be implemented in both the virtualbox section as well as qemu section.
