This change is to add ERR logs generated during warm-reboot script to syslog.
Currently the ERR logs are sent in stdout and a corresponding entry is not added to syslog.
This makes it difficult to debug issues when stdout is not readily available.

How I did it
Modified existing error function to add the log entry to syslog.

How to verify it
Verified manually on physical device
