Merge #19178: Make mininode_lock non-reentrant

Browse source 
62068381a3 [tests] Make mininode_lock non-reentrant (John Newbery)
c67c1f2c03 [tests] Don't call super twice in P2PTxInvStore.on_inv() (John Newbery)
9d80762fa0 [tests] Don't acquire mininode_lock twice in wait_for_broadcast() (John Newbery)
edae6075aa [tests] Only acquire lock once in p2p_compactblocks.py (John Newbery)

Pull request description:

  There's no need for mininode_lock to be reentrant.
  Use a simpler non-recursive lock.
