Merge #20138: net: Assume that SetCommonVersion is called at most once per peer
fa0f4157098ea68169ced44730986d0ed2c3a5aa net: Assume that SetCommonVersion is called at most once per peer (MarcoFalke)
Pull request description:
This restores the check removed in https://github.com/bitcoin/bitcoin/pull/17785#discussion_r503224381
Instead of using `error`, which was used previously, it uses a newly introduced `Assume()`. `error` had several issues:
* It logs unconditionally to the debug log
* It doesn't abort the program when the error is hit in tests
