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?
Yes. 4.4 only.
