[PATCH 02/12] blk-mq: expose stream write stats through debugfs

Useful to verify that things are working the way they should. Reading the file will return number of kb written to each stream. Writing the file will reset the statistics. No care is taken to ensure that we don't race on updates. Drivers will write to q->stream_writes[] if they handle a stream.
