It is technically possible to get a hung context without a valid
request. In such a situation, try to provide as much information in
the error capture as possible rather than just aborting and capturing
nothing.

Similarly, in the case of a engine reset failure the GuC is not able
to report the guilty context. So try a manual search instead of
reporting nothing.
