SeongJae Park 392b3d9d59 mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure
When a DAMOS-scheme DAMON sysfs directory setup fails after setup of
access_pattern/ directory, subdirectories of access_pattern/ directory are
not cleaned up.  As a result, DAMON sysfs interface is nearly broken until
the system reboots, and the memory for the unremoved directory is leaked.

Cleanup the directories under such failures.
