[stgt] iscsi: Move two messages to be logged as debug and not as errors

[Or Gerlitz]

Move two messages which are printed when connections are close from error
to debug level.

Without this change, a message currently gets logged every time an automatic
discovery process runs on the initiator node when using the discovery database.
When using multiple Control Ports, there are a lot of messages getting logged.
These essentially flood the /var/log/messages file on the initiator.
