    bnxt_en: Add missing 200G link speed reporting
    
    [ Upstream commit 581bce7bcb7e7f100908728e7b292e266c76895b ]
    
    bnxt_fw_to_ethtool_speed() is missing the case statement for 200G
    link speed reported by firmware.  As a result, ethtool will report
    unknown speed when the firmware reports 200G link speed.
    
    Fixes: 532262ba3b84 ("bnxt_en: ethtool: support PAM4 link speeds up to 200G")
