From: Alexander Lobakin <alexandr.lobakin at intel.com>
The 'if (ntu == rx_ring->count)' block in ice_alloc_rx_buffers_zc()
was previously residing in the loop, but after introducing the
batched interface it is used only to wrap-around the NTU descriptor,
thus no more need to assign 'xdp'.
Fixes: db804cfc21e9 ("ice: Use the xsk batched rx allocation interface")
