Merge #13205: [tests] Remove spurious error log in p2p_segwit.py

7384a35 [tests] Remove spurious error log in p2p_segwit.py (John Newbery)

Pull request description:

  Since 265d7c44b1aae06aee93f745a865807732218a73, when wait_until() fails,
  an error message is logged to the test framework log. This means that if
  wait_until() is called inside a try-except with the expectation that it
  will fail, a spurious error message is logged.

  wait_until() shouldn't be called with the expectation of failure. Fix
  that in p2p_segwit.py.
