[PATCH v9 5/7] vfio/type1: also check IRQ remapping capability at msi domain

On x86 IRQ remapping is abstracted by the IOMMU. On ARM this is abstracted by the msi controller. vfio_safe_irq_domain allows to check whether interrupts are "safe" for a given device. They are if the device does not use MSI or if the device uses MSI and the msi-parent controller supports IRQ
