Mark Knibbs 55dc68c012 USB: storage: Reject bogus max LUN values
Some mass storage devices return a bogus value in response to a Get Max LUN
request. The Iomega Jaz USB Adapter responds with 0x10, hence my recent
patch to use the US_FL_SINGLE_LUN quirk for it.

The USB MSC Bulk Only Transport document says "The device shall return one
byte of data that contains the maximum LUN supported by the device."

Since the LUN field in the command block wrapper is only 4 bits wide, it
might be helpful to report too-large LUN values in the kernel log, and
assume max LUN is actually 0. That could get some devices which currently
need the US_FL_SINGLE_LUN quirk to work.
