xen-netfront: Update features after registering netdev

commit 45c8184c1bed1ca8a7f02918552063a00b909bf5 upstream.

Update the features after calling register_netdev() otherwise the
device features are not set up correctly and it not possible to change
the MTU of the device. After this change, the features reported by
ethtool match the device's features before the commit which introduced
the issue and it is possible to change the device's MTU.
