Subject: [PATCH 17/20] drbd: propagate exposed UUIDs only into established
 connections

Sending into connections in C_CONNECTING state while we exchange the
feature and auth packets might interfere with exchanging those. I also
witnessed that it might block unexpectedly long (2 - 6 seconds),
holding the `connection->mutex[DATA_STREAM]` mutex and again causing
troubles with establishing connections.

This is a fix for commit 772e5b21d from April 2023
"drbd: Consider outdating a disk when more recent data is behind a diskless"
Released with of 9.1.15 and 9.2.4.
