For consistency, rename a JSON dump function by bdev_io_stat_dump_json() and change the parameter order. Other public APIs and function pointers in the generic bdev layer, spdk_bdev_dump_info_json(), spdk_bdev_fn_table::dump_info_json, and spdk_bdev_fn_table::write_config_json have a json_write_ctx pointer as the last parameter. For consistency, swap a statistics pointer and a json_write_ctx pointer. This is another preparation to extend I/O statistics to include error counters and module specific counters to output these via the bdev_get_iostat RPC.
