* Fix a deadlock if a panic happens during request handling
During request handling, if a panic is created, deferred functions are
run but otherwise execution stops. #5889 changed some locks to
non-defers but had the side effect of causing the read lock to not be
released if the request panicked. This fixes that and addresses a few
other potential places where things could go wrong:
1) In sealInitCommon we always now defer a function that unlocks the
read lock if it hasn't been unlocked already
2) In StepDown we defer the RUnlock but we also had two error cases that
were calling it manually. These are unlikely to be hit but if they were
I believe would cause a panic.
* Add panic recovery test
This allows us to truly delete policies when we've either invalidated it
(which since they're singletons/default should only happen when we're
doing a namespace delete) or are doing a namespace delete on the local
node.
