    LinuxKPI: pci: make sure a tailq and lock are initialized
    
    Move the initializations of the tailq and lock from
    linux_pci_attach_device() into lkpifill_pci_dev() so that they are
    initialized in all cases we create a device (see all the possible
    callers of lkpifill_pci_dev()).
