[dpdk-dev] [PATCH v16 3/8] net/virtio: fix aarch32 build

NEON vector path of the PMD needs aarch64 support. But it was
enabled for aarch32 build as well because aarch32 build had
cpu_family set to aarch64. So build for aarch32 will fail due
to unsupported intrinsics.

Fix aarch32 build by updating meson file to exclude NEON vector
implementation for aarch32.
