Subject: [PATCH] io: extend `AsyncFdReadyGuard` method lifetimes (#4267)

The implicit elided lifetimes of the `AsyncFd` references in return
types of methods on `AsyncFdReadyGuard` resolved to that of `&self`.
However that lifetime is smaller than `'a` since `self` contains an `&'a
AsyncFd` reference. This will not change so the change also does not
lessen future proofing.
