mm: shmem: fix getting incorrect lruvec when replacing a shmem folio

When testing shmem swapin, I encountered the warning below on my machine. 
The reason is that replacing an old shmem folio with a new one causes
mem_cgroup_migrate() to clear the old folio's memcg data.  As a result,
the old folio cannot get the correct memcg's lruvec needed to remove
itself from the LRU list when it is being freed.  This could lead to
possible serious problems, such as LRU list crashes due to holding the
wrong LRU lock, and incorrect LRU statistics.

To fix this issue, we can fallback to use the mem_cgroup_replace_folio()
to replace the old shmem folio.
