mm/damon/dbgfs: use operations id for knowing if the target has pid
DAMON debugfs interface depends on monitoring operations for virtual address spaces because it knows if the target has pid or not by seeing if the context is configured to use one of the virtual address space monitoring operation functions. We can replace that check with 'enum damon_ops_id' now, to make it independent. This commit makes the change.
