Fix early lints inside an async desugaring

Fixes #81531

When we buffer an early lint for a macro invocation,
we need to determine which NodeId to take the lint level from.
Currently, we use the `NodeId` of the closest def parent. However, if
the macro invocation is inside the desugared closure from an `async fn`
or async closure, that `NodeId` does not actually exist in the AST.

This commit explicitly calls `check_lint` for the `NodeId`s of closures
desugared from async expressions, ensuring that we do not miss any
buffered lints.
