[PATCH] rust: bindings: allow any number of params

["Michael S. Tsirkin" <mst@redhat.com>]

We are going to be adding more parameters, and this makes
rust unhappy:
    Functions with lots of parameters are considered bad style and reduce
    readability (“what does the 5th parameter mean?”). Consider grouping
    some parameters into a new type.

Specifically:

error: this function has too many arguments (8/7)

     = note: `-D clippy::too-many-arguments` implied by `-D warnings`
     = help: to override `-D warnings` add `#[allow(clippy::too_many_arguments)]`

I didn't want to disable this globally, so I just shut it off for this
file.
