    Debugged extra_specs_ops.py

    The current extra_specs_ops.py under nova/scheduler/filters has a bug:
    it crahses if <or> is not followed by a word. For example, if
    "<or> gpu <or>" is given in extra_specs, current code tries to pop a
    word after the second <or> that causes a crash. This patch lets it
    ignore the "<or>" keyword if no word follows the second "<or>" keyword.
