qemu: agent: Fix incorrect and weird debug/warning log entries

Replace the nonsensical debug statement by adding the expected event
code into the existing debug statement.

Since the monitor code always notifies the agent on guest
reboot/shutdown even if that was not initiated by the agent the warning
emitted later is bogus and pollutes the logs in such cases. Delete it
and keep just the original debug message where this info can be
inferred.
