    kernel - Disable MSIX mode in pci_teardown_msix()
    
    * Disable MSIX mode when pci_teardown_msix() is called.  This fixes
      issues on some BIOSes which do not fully clear the PCI hardware
      configuration when warm-booting.
    
      In particular, the NVME controller appears to have this issue with
      some laptops (HP Intel gen 9 and gen 10 laptops) whereby the MSI
      interrupt winds up being stuck on reboot.
