power: support missing Rx queue info

Browse Source 
Since some vdevs like virtio and vhost do not support rxq_info_get and
queue state inquiry, the error return value -ENOTSUP need to be ignored
when queue_stopped cannot get rx queue information and rx queue state.
This patch changes the return value of queue_stopped when
rte_eth_rx_queue_info_get return -ENOTSUP to support vdevs which cannot
provide rx queue information and rx queue state enable power management.

Fixes: 209fd585456c ("power: make ethdev power management thread unsafe")
