[dpdk-dev] [PATCH v4 1/2] examples/vhost_scsi: Don't build without virtio_scsi.h

From: Aaron Conole <aconole at redhat.com>

The vhost_scsi example code is set to build, even if the requisite header
file virtio_scsi.h isn't available.  This happens on some Ubuntu systems
when some versions of the libc-dev package aren't available.

Check whether the virtio_scsi.h file exists, and if not, set the build
flag to false.
