net/gve: support queue release

Add support for queue operations:
- rx_queue_release
- tx_queue_release

Previous gve_tx_queue_release and gve_rx_queue_release functions are
only used internally to release Rx/Tx queue related resources.

But when the queues or ports are required to re-config, both of the dev
ops tx_queue_release and ops rx_queue_release will be checked and then
called.

Without these two dev ops, the Rx/Tx queue struct will be set as NULL
directly.
