engine: Reduce the severity of check-upgrade log

When there is an attempt to check for an upgrade, while another process
is already running, the reported message is logged with an ERROR
severity. This specific message severity can be reduced to warning.

In addition, there is an inflation of error messages during the
process which can be reduced.
