vmscan,memcg: reintroduce sc->may_swap
Commit a6dc60f8975ad96d162915e07703a4439c80dcf0 ("vmscan: rename
sc.may_swap to may_unmap") removed the may_swap flag, but memcg had used
it as a flag for "we need to use swap?", as the name indicate.
And in the current implementation, memcg cannot reclaim mapped file
caches when mem+swap hits the limit.
re-introduce may_swap flag and handle it at get_scan_ratio(). This
patch doesn't influence any scan_control users other than memcg.
