T.J. Alumbaugh 451d7c42ea UPSTREAM: mm: multi-gen LRU: simplify lru_gen_look_around() 
Update the folio generation in place with or without
current->reclaim_state->mm_walk.  The LRU lock is held for longer, if
mm_walk is NULL and the number of folios to update is more than
PAGEVEC_SIZE.

This causes a measurable regression from the LRU lock contention during a
microbencmark.  But a tiny regression is not worth the complexity.
