f2fs: use ra_meta_pages to simplify readahead code in restore_node_summary
Use more common function ra_meta_pages() with META_POR to readahead node blocks
in restore_node_summary() instead of ra_sum_pages(), hence we can simplify the
readahead code there, and also we can remove unused function ra_sum_pages().
changes from v2:
o use invalidate_mapping_pages as before suggested by Changman Lee.
changes from v1:
o fix one bug when using truncate_inode_pages_range which is pointed out by
Jaegeuk Kim.
