libselinux/getconlist: report failures

Check the given context a priori, to print a more user friendly message,
opposed to a generic following get_ordered_context_list/_with_level
failure.

Notify the user about failures of get_ordered_context_list/_with_level,
so no-context-found and a failure results are distinguishable.
