media: ddbridge: fix buffer overflow in max_set_input_unlocked()
Picked up code parts introduced one smatch error:
drivers/media/pci/ddbridge/ddbridge-maxs8.c:163 max_set_input_unlocked() error: buffer overflow 'dev->link[port->lnr].lnb.voltage' 4 <= 255
Fix this by clamping the .lnb.voltage array access to 0-3 by "& 3"'ing
dvb->input.
