Support Linux v6.11

Update virtqueue setup to use the new virtio_find_vqs() interface
introduced in Linux commit c502eb8 ("virtio: Introduce struct
virtqueue_info and find_vqs_info() config op"), which now takes an array
of struct virtqueue_info instead of separate parameter arrays.

The legacy virtio_find_vqs() interface was replaced in Linux commit
6c85d6b ("virtio: Rename virtio_find_vqs_info() to virtio_find_vqs")
with a new implementation using struct virtqueue_info.

Since the original code relied on virtio_find_vqs() with implicit NULL
context, the ctx field is set to false to maintain equivalent behavior.
