[PATCH 5/7] net/iavf: disable runtime queue setup capability

[Dawid Wesierski]

From: Marek Kasiewicz <marek.kasiewicz at intel.com>

Remove the advertisement of RTE_ETH_DEV_CAPA_RUNTIME_RX_QUEUE_SETUP
and RTE_ETH_DEV_CAPA_RUNTIME_TX_QUEUE_SETUP capabilities from the
iavf VF driver.

Runtime queue setup on E810 VFs causes queue state corruption when
queues are dynamically reconfigured while the hardware rate limiter
is actively pacing TX queues. Queue configuration messages to the PF
via virtchnl can race with ongoing TX operations, leading to undefined
behavior.

By not advertising these capabilities, all queues are configured at
port start and remain stable throughout the port lifecycle.
