net/bnxt: fix autoneg on PAM4 links

Browse Source 
If autonegotiation was enabled, driver was not passing the
'auto_pam4_link_speeds' obtained during init and stored in bp->link_info
to bnxt_hwrm_port_phy_cfg(). This would result in an incorrect setting
being passed to the HW during PHY configuration. This in turn, would
result in invalid settings being retrieved and configured in subsequent
application loads resulting in launch failures.
