[BNX2]: Fix remote PHY media detection problems.
The remote PHY media type and link status can change between
->probe() and ->open(). For correct operation, we need to get the
new status again during ->open().
The ethtool link test and loopback test are also fixed to work with
remote PHY. PHY loopback is simply skipped when remote PHY is
present.
