on ARM, a devid field is populated in kvm_msi struct in case the
flag is set to KVM_MSI_VALID_DEVID. Let's propagate both flags and
devid field in kvm_kernel_irq_routing_entry.

v7 -> v8:
- adapt to changes in kvm_kernel_irq_routing_entry struct
v6 -> v7:
- use renamed msi_flags and msi_devid
- added Andre's R-b
v4 -> v5:
- Add Christoffer's R-b
v2 -> v3:
- do not set the type to KVM_IRQ_ROUTING_EXTENDED_MSI anymore as
suggested by Andre
- correct msi->flags check
- propagate the flags
