adapter_stop function is stopping the adapter service using
rte_service_runstate_set() api and waiting until
rte_service_may_be_active() api returns stopped state in an
infinite loop.

This results in hang issues if application calls
rte_service_lcore_stop() before adapter stop.

remove the state check after setting the service state which
avoids running into hang issues. This also makes tx adapter stop
inline with remaining adapters.

There are three different changes in this patch. But since they are quite small, it should be ok.
