blkcg: drop BLKCG_STAT_{PRIV|POL|OFF} macros
Now that all stat handling code lives in policy implementations, there's no need to encode policy ID in cft->private. * Export blkcg_prfill_[rw]stat() from blkcg, remove blkcg_print_[rw]stat(), and implement cfqg_print_[rw]stat() which use hard-code BLKIO_POLICY_PROP. * Use cft->private for offset of the target field directly and drop BLKCG_STAT_{PRIV|POL|OFF}().
