According to mass storage specification:
"Logical Unit Numbers on the device shall be numbered contiguously
starting from LUN 0 to a maximum LUN of 15 (Fh)"
So let's at least print a warning message that LUNs ids should be
contiguous.

I suggest just "LUNs" instead of "LUN ids" which sounds somewhat strange
(logical unit number ids, hm?).
