dev->nr_luns reports the total number of luns available in a device

When multiple channels are available, the offset is calculated from a

the total number of luns, we go out of bound when channel id > 0 and
causes the kernel to panic when we read a protected kernel memory area.
Added for 4.4, thanks.
