Description

Add a mutex to stop a race condition in the output manager error. Its possible that if more than on transactions happens in near the same time, the transactions will select the same inputs.

Description

Removes mutex added in #4613 

Motivation and Context
---
While the race condition is definitely possible in code, all code from the OMS runs synchronously, as shown by the fact that almost all functions have `&mut self` and rust blocks mut borrow across threads. This means that there is no race condition possible as this is all called synchronously.
