IB/qib: Do not write EEPROM
This changeset removes all the code that allows the driver to write to the EEPROM and update the recorded error counters and power on hours. These two stats are unused and writing them exposes a timing risk which could leave the EEPROM in a bad state preventing further normal operation of the HCA.
