PCI: designware: Make MSI ISR shared IRQ aware
On i.MX6 the host controller MSI IRQ is shared with PCI legacy INTD. Make sure we don't bail too early from the IRQ handler. The issue is fairly theoretical as it would require a system setup with a PCIe switch where one connected device is using legacy INTD and another one using MSI, but better fix it now.
