    LinuxKPI: 802.11 suspend/resume: fix the is_pci_dev check
    
    Shortly before I committed the works from a year ago, jhb added a
    function ("is_pci_device") so that the check against the devclass
    does not have to be coded in every driver.  Use this instead in main
    (and stable/15 in case the works get MFCed).
    
    At the same time this fixes the check (the old one was wrong) as we
    attach to the LinuxKPI 802.11 driver, e.g., iwlwifi and thus we need
    to check the parent of the parent and not just the parent to be
    of the devclass "pci" in the identify bus function.  The was the
    first error.  The second was (and this is why it worked) that we
    checked for == instead of != and so the wrong check became true again.
    
    Discussed with: jhb
    Fixes:          11d69a4558de ("LinuxKPI: 802.11: add support for s/r")
    MFC after:      3 days
    X-MFC after:    ffcf5e356644 ("pci: Add is_pci_device helper function")
