mm/memory-failure.c: avoid calling invalidate_inode_page() with unexpected pages

Since commit 042c4f3 ("mm/truncate: Inline invalidate_complete_page()
into its one caller"), invalidate_inode_page() can invalidate the pages
in the swap cache because the check of page->mapping != mapping is
removed.  But invalidate_inode_page() is not expected to deal with the
pages in swap cache.  Also non-lru movable page can reach here too.
They're not page cache pages.  Skip these pages by checking
PageSwapCache and PageLRU.
