Add version check to support compatibility

Reviewed kernel versions from 6.8 onward and found that
virtio_find_vqs changed in 6.11 and has remained stable since.
Introduced conditional logic to detect the running kernel version and
select the correct API usage accordingly. This ensures vwifi builds and
runs correctly across both pre-6.11 and 6.11+ kernels.
