netflow: Avoid (theoretically) looping 2**32 times.

If the netflow byte counter is UINT64_MAX, or at any rate much larger than
UINT32_MAX, netflow_expire() could loop for a very long time.  This commit
avoids that case.

This is only a theoretical bug fix.  I don't know of any actual bug that
would cause a counter to be that high.
