It is an option to keep using mask_msi_irq() without #ifdef, it seems in
newer version of the kernel mask_msi_irq() is already wrapper to the
pci_msi_mask_irq().

Although this may make the code simpler, it can break it if
mask_msi_irq() wrapper removed.

I would go with using mask_msi_irq() directly, but no strong opinion...
