From: Laurent Vivier <lvivier@redhat.com>

Following the same logic as for vhost-net-user and vhost-kernel,
enable vhost-net if vhost-net-vdpa is enabled and vhost-net is not
explicitly disabled.
See 299e6f19b3e2 ("vhost-net: revamp configure logic")

Autoselect VHOST if VHOST_VDPA is set
See 21c6b0c87e85 ("configure: simplify vhost condition with Kconfig")
See 2becc36a3e53 ("meson: infrastructure for building emulators"

Problems can be triggered using;
... --enable-vhost-vdpa --disable-vhost-user --disable-vhost-kernel ...

Fixes: 108a64818e69 ("vhost-vdpa: introduce vhost-vdpa backend")
