Cover letter [PATCH 0/6] samples/damon: handle damon_{start,stop}() failures
All DAMON sample modules are not correctly handling failures from damon_start(). Among those, mtier also has an additional problem for handling of damon_stop() failures. wsse and prcl also have a problem in their damon_call() failure handling. As a result, memory leaks, next DAMON operation disruptions, and use-after-free can happen. Fix those.
Note that only the damon_start() failure caused issues can reliably be reproduced. Reproducing those issues require the admin permission, though.
