Fix the warning: variable 'zone' is used
uninitialized whenever '?:' condition is true.

Fix that by preventing the code to reach
the last assertion. If the variable 'mirror'
is invalid, the assertion fails and we return
immediately.

This is not how you send a v4 patch...  v2 patches have to apply to the
original code and not on top of the patched code.

I sort of think you should find a different thing to work on.  This code
works fine as-is.  Just leave it and try to find a real bug and fix that
instead.
