kafka: fix data race on msgChan in connectExplicitTopics#4286
Conversation
Partition consumer goroutines were spawned before k.msgChan was assigned, causing a data race between the goroutine reads (line 104) and the subsequent write (line 304). Move the assignment before the spawn loop. Fixes CON-407
