Btrfs: allow running defrag in parallel to administrative tasks
Commit 5ac00add added a testnset mutex and code that disallows running administrative tasks in parallel. It is prevented that the device add/delete/balance/replace/resize operations are started in parallel. By mistake, the defragmentation operation was included in the check for mutually exclusiveness as well. This is fixed with this commit.
