quiche: fix lookup of transfer at multi

- refs #11449 where weirdness in quiche multi connection tranfers was
  observed
- fixes lookup of transfer for a quiche event to take the connection
  into account
- formerly, a transfer with the same stream_id, but on another connection
  could be found

Closes #11462
