restore return statements after calls to octave_base_stream::error

Unlike the global error function, the octave_base_stream::error
function simply sets some internal class error info and does return.

* oct-fstrm.cc, oct-stream.cc, oct-strstrm.cc: Rstore return
statements after calls to octave_base_stream::error.
