As far as the information I received from Immigration Officer at the Doha Int Airport; Someone has to completed 2 years from the exit date before allowing to come back and work in Qatar. Eventhough you didnt cancel your RP before, your RP will be automatically cancelled through the system once you out of Qatar max. 6 months.
In your case, if you would like to come back here, you should able to obtain NOC from your previous sponsor. Otherwise, it's gonna be impossible for your new employer to arrange for your working visa.
