This reverts commit 61ad844891.
This fix was trying to ensure that lock recovery response handling
can't run after farewell calls reclaim_rid() by jumping through a bunch
of hoops to tear down locking state as the first farewell request
arrived.
It introduced very slippery use after free during shutdown. It appears
that it was from drain_workqueue() previously being able to stop
chaining work. That's no longer possible when you're trying to drain
two workqueues that can queue work in each other.
We found a much clearer way to solve the problem so we can toss this.

Introduction
scoutfs is a clustered in-kernel Linux filesystem designed to support large archival systems. It features additional interfaces and metadata so that archive agents can perform their maintenance workflows without walking all the files in the namespace. Its cluster support lets deployments add nodes to satisfy archival tier bandwidth targets.
The design goal is to reach file populations in the trillions, with the archival bandwidth to match, while remaining operational and responsive.
Highlights of the design and implementation include:
- Fully consistent POSIX semantics between nodes
- Atomic transactions to maintain consistent persistent structures
- Integrated archival metadata replaces syncing to external databases
- Dynamic seperation of resources lets nodes write in parallel
- 64bit throughout; no limits on file or directory sizes or counts
- Open GPLv2 implementation
