ixgbe: convert to ndo_fix_features 

Private rx_csum flags are now duplicate of netdev->features &
NETIF_F_RXCSUM.  We remove those duplicates and now use the net_device_ops
ndo_set_features.  This was based on the original patch submitted by
Michal Miroslaw <mirq-linux@rere.qmqm.pl>.  I also removed the special
case not requiring a reset for X540 hardware.  It is needed just as it is
in 82599 hardware.
