nilfs2: simplify nilfs_get_page function
Implementation of nilfs_get_page() is a bit old as below:
- A common read_mapping_page inline function is now available instead
of its read_cache_page use.
- wait_on_page_locked() use in the function is eliminable since
read_cache_page function does the same thing through wait_on_page_read().
- PageUptodate() check is eliminable for the same reason.
This renews nilfs_get_page() based on these points.
