MathParser: Do not rewind the stream if we can't read from it

Browse Source 
If the stream is not good, we don't need to 'putback', because we didn't
read anything yet. If we now do rewind the stream, we are asking for
problems as in bug #8089.

This was introduced in [3cafb856\lyxgit] to fix bug #4318.
