net/mvpp2: fix Rx and Tx queue state

[ upstream commit 228056938a340205fd295814829782e3ea6e1a46 ]

The DPDK framework reports the queue state, which is stored in
dev->data->tx_queue_state and dev->data->rx_queue_state. The
state is maintained by the driver. Users may determine whether
a queue participates in packet forwarding based on the state.
Therefore, the driver needs to modify the queue state in time
according to the actual situation.

Fixes: 9ad9ff4 ("ethdev: add queue state in queried queue information")
