target: Set peripheral device type consistently in INQUIRY response
Current code sets the peripheral device type to 0x3f == "not present
unknown" for virtual LUN 0 for standard INQUIRY commands, but leaves it
as 0 == "connected direct access block" for VPD INQUIRY commands. This
is just because the check for LUN 0 only happens in some code paths.
Make our peripheral device type consistent by moving the LUN 0 check
into the common emulate_inquiry() code.
