Jason Wang 6a20f9fca3 vhost: initialize vq->nheads properly 
Commit 7918bb2d19c9 ("vhost: basic in order support") introduces
vq->nheads to store the number of batched used buffers per used elem
but it forgets to initialize the vq->nheads to NULL in
vhost_dev_init() this will cause kfree() that would try to free it
without be allocated if SET_OWNER is not called.
