Subject: [PATCH 4.19 34/84] PCI/MSI: Use msi_mask_irq() in pci_msi_shutdown()

From: Thomas Gleixner <tglx@...utronix.de>

commit d28d4ad2a1aef27458b3383725bb179beb8d015c upstream.

No point in using the raw write function from shutdown. Preparatory change
to introduce proper serialization for the msi_desc::masked cache.
