librustc_resolve: make sure pattern def gets recorded if `resolve_pat…

…h` returns `Err(true)`

In 1a374b8, (pr #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.

This commit fixes issue #33293.
