    bnxt_en: dcb: stop zeroing ETS and PFC config in bnxt_dcb_init()
    
    bnxt_dcb_init() currently pushes all-zero ETS and PFC settings to
    the firmware at every attach. This reserves bandwidth allocation
    for RoCE traffic, which prevents L2 traffic from reaching line rate.
    
    These settings should only be updated with valid values when the
    RoCE driver is loaded. Therefore, we should stop programming them
    during bnxt_dcb_init().
