mm: shmem: return number of pages beeing freed in shmem_free_swap
Both shmem_free_swap callers expect the number of pages being freed. In
the large folios context, this needs to support larger values other than 0
(used as 1 page being freed) and -ENOENT (used as 0 pages being freed).
In preparation for large folios adoption, make shmem_free_swap routine
return the number of pages being freed. So, returning 0 in this context,
means 0 pages being freed.
While we are at it, changing to use free_swap_and_cache_nr() to free large
order swap entry by Baolin Wang.
