vfio-pci: Don't use kvm_irqchip_in_kernel
kvm_irqchip_in_kernel() has an architecture specific meaning, so we shouldn't be using it to determine whether to enabled KVM INTx bypass. kvm_irqfds_enabled() seems most appropriate. Also use this to protect our other call to kvm_check_extension() as that explodes when KVM isn't enabled. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Cc: qemu-stable@nongnu.org
