[PATCH] blk-ioprio: fix stale prio_policy kernel-doc

[PATCH] blk-ioprio: fix stale prio_policy kernel-doc

[Guopeng Zhang]

From: Guopeng Zhang <zhangguopeng@kylinos.cn>

Fix two stale kernel-doc entries in blk-ioprio. The
POLICY_PROMOTE_TO_RT comment should describe promotion from
non-IOPRIO_CLASS_RT classes, and @prio_policy stores enum prio_policy
values rather than IOPRIO_CLASS_* values.
