kernel32: Prevent endless loop if NtQuerySystemInformation fails

[Sebastian Lackner]

The current implementation of fetch_process_thread in toolhelp.c never
fails - because it just retries forever. I don't think that this was the
original intention, at least it looks suspicious. This patch returns
with FALSE if NtQuerySystemInformation fails with an unknown status code.
