Rollup merge of #122360 - veera-sivarajan:bugfix-121941, r=compiler-e…
…rrors Don't Create `ParamCandidate` When Obligation Contains Errors Fixes #121941 I'm not sure if I understand this correctly but this bug was caused by an error type incorrectly matching against `ParamCandidate`. This was introduced by the changes made in #72621 (figured using cargo-bisect-rustc). This PR fixes it by skipping `ParamCandidate` generation when an error type is involved. Also, this is similar to #73005 but addresses `ParamCandidate` instead of `ImplCandidate`.
