OVS main thread is calling rte_eth_dev_configure()...iavf_queues_req_reset() and is getting stuck in rte_eal_alarm_cancel() waiting for alarms to be cancelled.
eal-intr-thread is stuck in application callback as it is requesting reconfiguration and waiting for current configure to be completed in the main thread.

net/iavf: fix abnormal disable HW interrupt
[ upstream commit 675a104e2e940ec476e8b469725e8465d01c0098 ]
For command VIRTCHNL_OP_REQUEST_QUEUES, polling access to the admin queue has the issue of access overruns after disabling interrupt. That results in FW disabling HW interrupt for protection purposes.
The updates/changes in this patch:
1. Remove the polling admin queue processing and use the generic interrupt processing instead.
2. Release redundant queue resource before stopping processing interrupt events.
