Driver aborts during OP_MSG bulk write if command fails mid batch

      The bug report of CDRIVER-3195 appears to be due to mishandling of OP_MSG bulk writes when we fail to write to the server socket in the middle of a batch.

      result->must_stop, which was introduced in CDRIVER-1556, indicates if a bulk write should stop attempting commands due to a socket disconnect. It is checked in _mongoc_write_opquery but not checked in _mongoc_write_opmsg. So we attempt the sending next OP_MSG without having a socket.

      I've reproduced on 1.13.1 and master, but I suspect this goes back to our initial OP_MSG support in 1.9.
