Subject: [PATCH] net_util: queue_pair: Remove unnecessary mut from reference

warning: this argument is a mutable reference, but not used mutably
   --> net_util/src/queue_pair.rs:167:14
    |
167 |         tap: &mut Tap,
    |              ^^^^^^^^ help: consider changing to: `&Tap`
    |
    = warning: changing this function will impact semver compatibility
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#needless_pass_by_ref_mut
