[PATCH] btrfs: no need to check if tgt_device is null

[Anand Jain <anand.jain@oracle.com>]

We don't have to check if tgt_device is null and then delete
it, because there wouldn't be a case where tgt_device will
be null in a mounted context. If the replacement is already
canceled then we won't be here, since there is a switch above
to deviate.
