Improve the error handling in passive TFO test to check the return value
from sendto(), and to fail if read() or fprintf() failed.

You propose to adjust error detection and corresponding exception handling another bit.
How do you think about to take also another look if further function implementations
would be similarly affected?

Thank you for the suggestion. The first objective of this series is to
fix the misleading behavior that was caused by the following bug.
Therefore, I intentionally limited the scope of this patch to the
affected or closely related functions.

I believe this is sufficient to prevent it from showing misleading error
messages when the test fails.

Thank you,
Yohei
