sfc: ensure recovery after allocation failures
After failing to allocate a receive buffer the driver may fail to ever
request additional allocations. EF10 NICs require new receive buffers to
be pushed in batches of eight or more. The test for whether a slow fill
should be scheduled failed to take account of this. There is little
downside to *always* requesting a slow fill if we failed to allocate a
buffer, so the condition has been removed completely. The timer that
triggers the request for a refill has also been shortened.
