fuse: fix page invalidation
Other than truncate, there are two cases, when fuse tries to get rid of cached pages: a) in open, if KEEP_CACHE flag is not set b) in getattr, if file size changed spontaneously Until now invalidate_mapping_pages() were used, which didn't get rid of mapped pages. This is wrong, and becomes more wrong as dirty pages are introduced. So instead properly invalidate all pages with invalidate_inode_pages2().
