Steps to reproduce:

1. Create a Pipeline with the fellow script

   pipeline{
       
       agent {
           label "test-pod"
       }
       
       stages {
           stage("Sleep") {
               steps {
                   sh "sleep 1000"
               }
           }    
       }
   }
   

1. Run the Pipeline and waiting for agent pod to start
2. Reboot the node which the agent pod has been assigned to

Result:

SlaveComputer is marked as offline and never get deleted even after we delete the pod. Build will also not failed and run forever.

Expected Result:

SlaveComputer is deleted and the build is failed.
