resolve: record pattern def when `resolve_pattern` returns `Err(true)`

I propose a fix for issue rust-lang#33293.

In 1a374b8, (pr rust-lang#33046) fixed the error reporting of a specific case, but the change that was introduced did not make sure that `record_def` was called in all cases, which lead to an ICE in [1].
This change restores the original `else` case, but keeps the changes that were committed in 1a374b8.
