IB/qib: Hold links until tuning data is available

Browse source

Hold the link state machine until the tuning data is read from the
QSFP EEPROM so correct tuning settings are applied before the state
machine attempts to bring the link up.  Link is also held on cable
unplug in case a different cable is used.
