[PATCH v2] mm/swap.c: make functions and their kernel-doc agree

[Randy Dunlap <rdunlap@infradead.org>]

From: Randy Dunlap <rdunlap@infradead.org>

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

Fixes: 67fd707f4681
    ("mm: remove nr_pages argument from pagevec_lookup_{,range}_tag()")
