scsi: devinfo: Add BLIST_SKIP_IO_HINTS for Iomega ZIP

The Iomega ZIP 100 (Z100P2) can't process IO Advice Hints Grouping mode
page query. It immediately switches to the status phase 0xb8 after
receiving the subpage code 0x05 of MODE_SENSE_10 command, which fails
imm_out() and turns into DID_ERROR of this command, which leads to unusable
device. This was tested with an Iomega ZIP 100 (Z100P2) connected with a
StarTech PEX1P2 AX99100 PCIe parallel port card.

Prior to this fix, Test Unit Ready fails and the drive can't be used:
        IMM: returned SCSI status b8
        sd 7:0:6:0: [sdh] Test Unit Ready failed: Result: hostbyte=0x01 driverbyte=DRIVER_OK
