The backport of commit 8f5a695d99000fc ("xen/blkfront: don't take local copy of a request from the ring page") to stable 4.4 kernel introduced a bug when adding the needed blkif_ring_get_request() function, as info->ring.req_prod_pvt was incremented twice now.

Fix that be deleting the now superfluous increments after calling that function.

So this is only needed in 4.4.y? No other backports were incorrect?
