Levi Yun 1c8e2349f2 damon/sysfs: fix possible memleak on damon_sysfs_add_target 
When damon_sysfs_add_target couldn't find proper task, New allocated
damon_target structure isn't registered yet, So, it's impossible to free
new allocated one by damon_sysfs_destroy_targets.

By calling damon_add_target as soon as allocating new target, Fix this
possible memory leak.
