fac96d026511f22f0202ce3631a38be0e990555f p2p: Limit m_block_inv_mutex (MarcoFalke)

Pull request description:

  Keeping the lock longer than needed is confusing to reviewers and thread analysis. For example, keeping the lock while appending tx-invs, which requires the mempool lock, will tell thread analysis tools an incorrect lock order of `(1) m_block_inv_mutex, (2) pool.cs`.
