Fix format of pref64 option.
The lifetime is not shifted left three bits, It's divided by 8
(so shifted right 3 bits), but it's also a 13-bit integer that
occupies the beginning of a 16-bit field. So it's effectively
the same as a 16-bit integer with the least significant 3 bits
replaced by the plc.
