[PATCH v3 7/7] scsi: scsi_devinfo: extend BLIST_NO_LUN_1F to MATSHITA and NEC PD-1 variants

[Phil Pemberton <philpem@philpem.me.uk>]

The Panasonic LF-1095/LF-1195 PD/CD combo drive was sold under three
OEM identities: COMPAQ "PD-1", MATSHITA "PD-1", and NEC "PD-1 ODX654P".
All three are the same drive mechanism with the same firmware family,
so they should share the BLIST_NO_LUN_1F quirk that was applied to the
COMPAQ variant: PDT 0x1f / PQ 0 INQUIRY responses on non-existent LUNs
are treated as "LUN not present" rather than as a phantom sdev.

This patch is offered for completeness.  It has not been tested on the
MATSHITA or NEC variants -- the author only has access to the COMPAQ
unit -- but the drives are functionally identical and the flag is a
no-op on devices that do not exhibit the PDT 0x1f response.  Drop or
hold this patch if confirmation on real hardware is preferred before
extending the quirk.
