Reinstate instance locked error logging
Reinstate instance locked error logging

Commit eebc64f removed some error logging, presumably by mistake.

If checks_instance_state fails, and the action blocked, users aren't
notified but the error is logged for admins. Changing this behavior
clearly wasn't the intent of the no-db-messaging commit.
