SeongJae ParkandGreg Kroah-Hartman 4396464434 mm/damon/sysfs: cleanup attrs subdirs on context dir setup failure 
commit 9814cc832b upstream.

When a context DAMON sysfs directory setup is failed after setup of attrs/
directory, subdirectories of attrs/ 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.

Fixes: c951cd3b89 ("mm/damon: implement a minimal stub for sysfs-based DAMON interface")
