sierra/objs_lsl/mnln.asm: Use division quotient, not remainder
It calls a routine twice to make a division (L125C) but doesn't check
the right register for the result. The result is returned in reg U and
the remainder in reg D but the procedure expect the result to be returned
in reg D. The divison routine seems to be correct because it is properly
used elsewhere in the code.
