[PATCH ha-manager 5/5] lrm: stop and restart panicked VMs to keep the "started" state

[Kaiyang Wu <wukaiyang2003@gmail.com>]

When a VM panics, 'check_running()' returns -1 to indicate the panicked
state. Stop the service first since panicked VMs are still running, then
restart the service to keep the "started" state.
