Vineeth Remanan Pillai 21f79ae43f xen-netfront: Rework the fix for Rx stall during OOM and network stress ...

commit 538d92912d upstream.

The commit 90c311b0ee ("xen-netfront: Fix Rx stall during network
stress and OOM") caused the refill timer to be triggerred almost on
all invocations of xennet_alloc_rx_buffers for certain workloads.
This reworks the fix by reverting to the old behaviour and taking into
consideration the skb allocation failure. Refill timer is now triggered
on insufficient requests or skb allocation failure.
