mm/damon/sysfs-schemes: put damos dests dir after removing its files
damon_sysfs_scheme_rm_dirs() puts dests directory kobject before removing
its internal files. Sincee putting the kobject frees its container
struct, and the internal files removal accesses the container,
use-after-free happens. Fix it by putting the reference _after_ removing
the files.
