[SCSI] Blacklist entry for HP dat changer

after upgrading our SUN E250 from 2.4 to 2.6 I'm seeing following error
when the HP DDS4 DAT changer gets probed:

scsi: host 1 channel 0 id 5 lun16777216 has a LUN larger than allowed by
the host adapter

The device is connected to a symbios 875 host. I've talked to Willy
about the problem, and he asked me to try to blacklist the device
for reportlun. I did that with the patch below and it solved the
problem. It now gets properly detected:
