a09e260c15 refacotor: simply RecursiveMutex -> Mutex (pasta)
Pull request description:
## What was done?
This PR is a simpler version of https://github.com/dashpay/dash/pull/5954; it is simply a recursiveMutex -> Mutex PR; as I think some of the scope minimization in the other PR introduced test failures (appears there are undocumented mutex dependancies)
## How Has This Been Tested?
CI TBD
## Breaking Changes
None
