block: account statistics for passthrough requests
Presently, passthrough requests are not accounted for because blk_do_io_stat() expressly rejects them. Based on some digging in the history, this doesn't seem like a concious decision but one that evolved from the change from blk_fs_request() to blk_rq_is_passthrough(). To support this, call blk_account_io_start() in blk_execute_rq_nowait() and remove the passthrough check in blk_do_io_stat().
