[PATCH] drivers: pci: Add prototype declarations of function inappropriate header

[Rashika Kheria]

Add prototype declarations of functions arch_msi_mask_irq() and
arch_msix_mask_irq() to header file include/linux/msi.h.

This eliminates the following warning in msi.c:
drivers/pci/msi.c:202:12: warning: no previous prototype for âarch_msi_mask_irqâ [-Wmissing-prototypes]
drivers/pci/msi.c:232:12: warning: no previous prototype for âarch_msix_mask_irqâ [-Wmissing-prototypes]
