vhost: initialize log eventfd context pointer
vq log eventfd context pointer needs to be initialized, otherwise operation may fail or oops if log is enabled but log eventfd not set by userspace. When log_ctx for device is created, it is copied to the vq. This reset was missing. Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
