bnxt_en: Refactor the initialization of the ethtool link settings.
Refactor this logic in bnxt_probe_phy() into a separate function bnxt_init_ethtool_link_settings(). It used to be that the settable link settings will never be changed without going through ethtool. So we only needed to do this once in bnxt_probe_phy(). Now, another function sharing the port may change it and we may need to re-initialize the ethtool settings again in run-time.
