vhost-net: disable when cross-endian
As of today, vhost assumes guest and host have the same endianness. This is definitely not compatible with modern PPC64 and ARM that can change endianness at runtime. Let's disable vhost-net and print an error message when we detect such a case: qemu-system-ppc64: vhost-net does not support cross-endian qemu-system-ppc64: unable to start vhost net: 38: falling back on userspace virtio This way users can continue to run VMs without changing their setup and have a chance to know that performance will be impacted.
