mm/damon/sysfs: use damon_call() for commit_schemes_quota_goals

Browse Source 
DAMON sysfs interface uses damon_callback with its own synchronization
facility to handle commit_schemes_quota_goals command.  But damon_call()
can support the use case without the additional synchronizations.  Convert
the code to use damon_call() instead.
