`#[pin_data]` inserts outlive bounds between lifetimes to allow closure callbacks to rely on their relationship. In some cases, these relations are implied by fields, and Rust generates `explicit_outlives_requirements` allow-by-default lint, which is turned out by kernel as part of rust-2018-idioms lint group. As `#[pin_data]` is a proc macro and it cannot know if the bounds are already implied, suppress such lints for generated code.
