stdio/lib_libfread: Fix buffer overflow issue

If the gulp size in the stdio buffer the remaining user buffer size it will:
- Corrupt memory in dest (user memory) and
- Keep corrupting KERNEL memory via the stdio character buffer until the
  whole system crashes, as the 'remaining' count underflows

This patch fixes this behavior.
