Merge #15654: net: Remove unused unsanitized user agent string CNode::strSubVer

Browse Source 
fa8548c5d1 net: Remove unused unsanitized user agent string CNode::strSubVer (MarcoFalke)

Pull request description:

  I fail to see a use case for this unsanitized byte array. In fact this can easily be confused with `cleanSubVer` and be displayed to the user (or logged) by a simple typo that is hard to find in review.
