[PATCH 7/9] btrfs: quiten warn if the replace is canceled at finish

[Anand Jain]

When we successfully cancel the replace its scrub returns -ECANCELED,
which then passed to btrfs_dev_replace_finishing(), it cleans up based
on the scrub returned status and propagates the same -ECANCELED back
the parent function. As of now only user can cancel the replace-scrub,
so its ok to quieten the warn here.
