xen-blkfront: set queue paravirt flag
Xen's blkfront sets noop as the default I/O scheduler at initialization time to avoid elevator overheads such as idling, but with the advent of basic disk profiling capabilities this is not necessary anymore. We should just tell the block layer that we are a paravirt front-end driver and the elevator will automatically make the necessary adjustments.
