mm: shmem: use swap_free_nr() to free shmem swap entries
As a preparation for supporting shmem large folio swapout, use
swap_free_nr() to free some continuous swap entries of the shmem large
folio when the large folio was swapped in from the swap cache. In
addition, the index should also be round down to the number of pages when
adding the swapin folio into the pagecache.
