[PATCH v3 2/2] PCI: dwc: Cleanup in dw_pcie_ep_raise_msi_irq()

[Dan Carpenter]

I recently changed the code in dw_pcie_ep_raise_msix_irq() to use
ALIGN_DOWN(). The code in dw_pcie_ep_raise_msi_irq() is similar so
update it to match as well.  (No effect on runtime, just a cleanup).

v2: Add this patch
v3: Use ALIGN_DOWN() as a style improvement
