net/bnxt: force PHY update on certain configurations

Device is not obliged link down in certain scenarios, even
when forced. When FW does not allow any user other than the BMC
to shutdown the port, bnxt_get_hwrm_link_config() call always
returns link up. Force phy update always in that case,
else user configuration for speed/autoneg would not get applied
correctly.
