Ilya Maximets ebd02c060a vhost: check ring descriptor address 
In current implementation vhost will crash with segmentation fault
if malicious or buggy virtio application breaks addresses of descriptors.

Before commit 0823c1cb0a ("vhost: workaround stale vring base")
this crash was reproducible even with normal DPDK application that tries
to change number of virtqueues dynamically inside VM.

Fix that by checking addresses of descriptors before using.
