x86: CPA: remove BUG_ON for LRU/Compound pages
New implementation does not use lru for anything so there is no need to reject pages that are in the LRU. Similar for compound pages (which were checked because they also use page->lru) [ tglx@linutronix.de: removed unused variable ] Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
