mm/damon/core: return an error from damos_commit_filter_arg()

damos_commit_filter_arg() is supposed to always succeed.  It may not in
future, for example, if the given filter is invalid.  Prepare the case by
modifying its signature to return an error when it failed.  Also pipe the
return value to its callers and let them handle the error.
