SeongJae Park 94b45fddc2 mm/damon/tests/core-kunit: handle memory alloc failure from damon_test_aggregate() 
commit f79f2fc44e upstream.

damon_test_aggregate() is assuming all dynamic memory allocation in it
will succeed.  Those are indeed likely in the real use cases since those
allocations are too small to fail, but theoretically those could fail.  In
the case, inappropriate memory access can happen.  Fix it by appropriately
cleanup pre-allocated memory and skip the execution of the remaining tests
in the failure cases.
