btrfs: scrub: fix a return value overwrite in scrub_stripe()
[RETURN VALUE OVERWRITE]
Inside scrub_stripe(), we would submit all the remaining stripes after
iterating all extents.
But since flush_scrub_stripes() can return error, we need to avoid
overwriting the existing @ret if there is any error.
However the existing check is doing the wrong check:
ret2 = flush_scrub_stripes();
if (!ret2)
ret = ret2;
This would overwrite the existing @ret to 0 as long as the final flush
detects no critical errors.
[FIX]
We should check @ret other than @ret2 in that case.
Fixes: 8eb3dd17eadd ("btrfs: dev-replace: error out if we have unrepaired metadata error during")
