Sander van Harmelen b346f7fd45 x/tools/cmd/gopls: prevent nil pointer dereferences
The `files` slice is used twice. First it's used to get all results from `ph.Parse`, and then it's reused to filter all `nil` values (which may have been returned by the `ph.Parse` method).

After the loop to "filter" out all the `nil` values, we also need to strip the remaining values.

I also changed the ordering so that we first check the errors and
only then perform this loop. That way the code will return earlier
when the context was canceled.

Partially fixes #33531 by prevention the panic reported in that issue.
