mm/swap.c: make functions and their kernel-doc agree

Fix some basic kernel-doc notation in mm/swap.c:

 - for function lru_cache_add_anon(), make its kernel-doc function name
   match its function name and change colon to hyphen following the
   function name

 - for function pagevec_lookup_entries(), change the function parameter
   name from nr_pages to nr_entries since that is more descriptive of
   what the parameter actually is and then it matches the kernel-doc
   comments also

Fix function kernel-doc to match the change in commit 67fd707f4681:

 - drop the kernel-doc notation for @nr_pages from
   pagevec_lookup_range() and correct the function description for that
   change
