Commit 565523cb allowed processing of further channel names given to the
JOIN command when a single name was invalid.

After this patch, the JOIN command handler continues to process channel
name lists even after errors like "channel is full", "too many channels",
and the like and generates appropriate error messages for all the
channels given by the client.
