[PATCH 10/15] Btrfs: Avoid trustless page-level-repair in dev-replace

[Zhaolei <zhaolei@cn.fujitsu.com>]

From: Zhao Lei <zhaolei@cn.fujitsu.com>

Current code of page level repair for dev-replace can only support
io-error, we can't use it in checksum-fail case.

We can skip this kind of repair in dev-replace just as we in scrub.
