filemap: fix the last_index of mm_filemap_get_pages
In commit b6273b55d885 ("filemap: add trace events for get_pages,
map_pages, and fault"), mm_filemap_get_pages was added to trace page cache
access. However, it tracks an extra page beyond the end of the accessed
range. This patch fixes it by replacing last_index with last_index - 1.
