remove unneeded usages of isErrorResponse (#164609)

`data.search` uses [poll_search](https://github.com/elastic/kibana/blob/main/src/plugins/data/common/search/poll_search.ts) to fetch data. `poll_search` checks for `isErrorResponse` and throws when`isErrorResponse` is true. **Note** `searchSource.search` uses `data.search` to perform searches. ```javascript return from(search()).pipe( expand(() => { const elapsedTime = Date.now() - startTime; return timer(getPollInterval(elapsedTime)).pipe(switchMap(search)); }), tap((response) => { if (isErrorResponse(response)) { throw response ? new Error('Received partial response') : new AbortError(); } }), takeWhile<Response>(isPartialResponse, true), takeUntil<Response>(aborted$) ); ``` Subscribers to `data.search` and `searchSource.search` do not need to check for `isErrorResponse` in `next`. `poll_search` has already thrown then the response is `isErrorResponse` so these checks are dead code blocks that are never executed. This PR removes these dead code blocks. Breaking this change out of https://github.com/elastic/kibana/pull/164506 so that it can be reviewed in isolated. --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com>
