xentop.c trivial fix

[Peter <p.spamcatcher@rimuhosting.com>]

Hi.

I run:
xentop --delay=30 --iterations 2 --batch

I get output, 30 second delay, output, 30 second delay, exit.

I want output, 30 seconds delay, output, exit.

The following patch implements that behavior and I think this is likely
the desired behavior anyway.  i.e. just a trivial bug in code.
