[PATCH] vhost: move is_le setup to the backend
...fix endianness when accessing the vring via the cpu_to_vhost16() and vhost16_to_cpu() helpers in the following cases: 1) host is big endian and device is modern virtio 2) host has cross-endian support and device is legacy virtio with a different endianness than the host Both cases rely on the VHOST_SET_FEATURES ioctl, but 2) also needs the VHOST_SET_VRING_ENDIAN ioctl to be called by userspace. Since vq->is_le is only needed when the backend is active, it was decided to set it at backend start. This is currently done in vhost_init_used()->vhost_init_is_le() but it obfuscates the core vhost code....
