    net/iavf: fix duplicate VF reset during PF reset recovery
    
    During PF initiated reset recovery, iavf_dev_close() sends an
    extra 'VIRTCHNL_OP_RESET_VF' while recovery is already in progress.
    That second reset can leave PF/VF virtchnl state inconsistent and
    cause 'VIRTCHNL_OP_CONFIG_VSI_QUEUES' to fail with 'ERR_PARAM' after
    ToR link flap/power-cycle, leaving the VF unable to recover.
    This results in connection loss.
    
    This patch introduces a new flag 'pf_reset_in_progress', which
    is set only when iavf_handle_hw_reset() is entered for a
    PF-initiated reset (vf_initiated_reset is false), and
    it is cleared on exit.
    The aforesaid flag is used to prevent sending close-time VF
    reset and related close-time virtchnl operation messages to the
    AdminQ when PF triggered reset recovery is set.
    This is done to avoid duplicate VF reset requests while preserving
    normal behavior for application-driven close or VF-initiated reinit.
    
    Fixes: 675a104e2e94 ("net/iavf: fix abnormal disable HW interrupt")
    Fixes: b34fe66ea893 ("net/iavf: delay VF reset command")
    Fixes: 5e03e316c753 ("net/iavf: handle virtchnl event message without interrupt")
