Stream: allow waiting on a blocked QUIC stream (ticket #2479). Previously, waiting on a shared connection was not allowed, because the only type of such connection was plain UDP. However, QUIC stream connections are also shared since they share socket descriptor with the listen connection. Meanwhile, it's perfectly normal to wait on such connections. The issue manifested itself with stream write errors when the amount of data exceeded stream buffer size or flow control. Now no error is triggered and Stream write module is allowed to wait for buffer space to become available.
