memcg: workingset: remove folio_memcg_rcu usage
The function workingset_activation() is called from folio_mark_accessed()
with the guarantee that the given folio can not be freed under us in
workingset_activation(). In addition, the association of the folio and
its memcg can not be broken here because charge migration is no more.
There is no need to use folio_memcg_rcu. Simply use folio_memcg_charged()
because that is what this function cares about.
[[email protected]: provide folio_memcg_charged stub for CONFIG_MEMCG=n]
