mm/damon/sysfs: do not ignore callback's return value in damon_sysfs_damon_call()
The callback return value is ignored in damon_sysfs_damon_call(), which
means that it is not possible to detect invalid user input when writing
commands such as 'commit' to
/sys/kernel/mm/damon/admin/kdamonds/<K>/state. Fix it.
