x86, pat: Fix cacheflush address in change_page_attr_set_clr()
Fix address passed to cpa_flush_range() when changing page
attributes from WB to UC. The address (*addr) is
modified by __change_page_attr_set_clr(). The result is that
the pages being flushed start at the _end_ of the changed range
instead of the beginning.
This should be considered for 2.6.30-stable and 2.6.31-stable.
