ice: remove dead store on XSK hotpath 

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: db804cfc21 ("ice: Use the xsk batched rx allocation interface")
