net/memif: fix Rx and Tx queue state

[ upstream commit 1b5e3493b8058f3980a14d00ecd31e2bbe88d535 ]

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")
