mm/damon/sysfs: simplify the judgement whether kdamonds are busy
It is unnecessary to get the number of the running kdamond to judge
whether kdamonds are busy. Here we can use the
damon_sysfs_kdamond_running() helper and return -EBUSY directly when
finding a running kdamond. Meanwhile, merging with the judgement that a
kdamond has current sysfs command callback request to make the code more
clear.
