Drop unnecessary lifetime notations

Rust can automatically deduce lifetimes in some cases ("lifetime
elision"). While adding unnecessary lifetime annotations is not
incorrect, it can make it harder to follow the code: why is there a
lifetime annotation here? What is the reason why it's needed? Is
something unusual going on.

This removes a few unnecessary lifetime annotations, as found by the
clippy lint needless_lifetimes:
