Use the return value from bnxt_get_media() to determine the port and
link modes.  bnxt_get_media() returns the proper BNXT_MEDIA_KR when
the PHY is backplane.  This will correct the ethtool settings for
backplane devices.

Fixes: 5d4e1bf60664 ("bnxt_en: extend media types to supported and autoneg modes")
