e1000e: convert to netdev features/hw_features API

Browse Source 
Private rx_csum flags are now duplicate of netdev->features &
NETIF_F_RXCSUM.  Remove those duplicates and use the net_device_ops
ndo_set_features.  This is based on the original patch submitted by
Michał Mirosław <mirq-linux@rere.qmqm.pl>
