Cover letter [PATCH 0/2] mm/damon/sysfs: fix commit test damon_ctx [de]allocation

DAMON sysfs interface dynamically allocates and uses a damon_ctx object for testing if given inputs for online DAMON parameters update is valid. The object is being used without an allocation failure check, and leaked when the test succeeds. Fix the two bugs.
