The commit flag is also used to determine if the hierarchy configuration needs to be cleared. When DPDK exits, it always stops the device first and also resets the commit flag result in the hierarchy configuration is not cleared. This commit changes DPDK to not reset the commit flag when the device is stopped. And we prevent additional commit when device is running by only checking the stop flag.
