Subject: [PATCH] virtio-devices: Fix clippy::ptr-arg issue

error: writing `&mut Vec` instead of `&mut [_]` involves a new object
where a slice will do

Vec<Queue<GuestMemoryAtomic<GuestMemoryMmap>>>,
   |                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
help: change this to: `&mut [Queue<GuestMemoryAtomic<GuestMemoryMmap>>]`
