mm/vmscan.c: fix recent_rotated history
Johannes pointed out that after commit886cf1901d
("mm: move recent_rotated pages calculation to shrink_inactive_list()") we lost all zone_reclaim_stat::recent_rotated history. This fixes it. Link: http://lkml.kernel.org/r/155905972210.26456.11178359431724024112.stgit@localhost.localdomain Fixes:886cf1901d
