i40e: Fix receive buffer starvation for AF_XDP 

Magnus's fix to resolve a potential receive buffer starvation for AF_XDP
got applied to both the i40e_xsk_umem_enable/disable() functions, when it
should have only been applied to the "enable".  So clean up the undesired
code in the disable function.
