PCI/MSI: Rename mask/unmask_msi_irq treewide

The PCI/MSI irq chip callbacks mask/unmask_msi_irq have been renamed
to pci_msi_mask/unmask_irq to mark them PCI specific. Rename all usage
sites. The conversion helper functions are kept around to avoid
conflicts in next and will be removed after merging into mainline.

Coccinelle assisted conversion. No functional change.
