    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 interr=
upt
    processing instead.
    2. Release redundant queue resource before stopping processing interrupt
    events.

    Fixes: 22b123a36d07 ("net/avf: initialize PMD")
    Fixes: ef807926e148 ("net/iavf: support requesting additional queu=
es from
PF")
    Fixes: 84108425054a ("net/iavf: support asynchronous virtual chann=
el
message")
