Jay Zhou 5303a48b53 vhost: add virtio crypto header file 
Since the linux kernel header file virtio_crypto.h has been merged
in 4.9, if we include this header file directly, compilation will be
failed in the old kernels' environment, e.g. the vhost crypto backend
series.
Adding virtio_crypto.h in librte_vhost to make old kernels happy.
