mm/damon/sysfs-schemes: remove unnecessary online tuning handling code

damon/sysfs-schemes.c contains code for handling of online DAMON
parameters update edge cases.  The logics are no more necessary since
damon_commit_ctx() and damon_commit_quota_goals() takes care of the cases.
Remove the unnecessary code.
