mm/damon/sysfs: implement a kdamond command for updating schemes' effective quotas
Implement yet another kdamond 'state' file input command, namely
'update_schemes_effective_quotas'. If it is written, the
'effective_bytes' files of the kdamond will be updated to provide the
current effective size quota of each scheme in bytes.
