mm/damon/vaddr: add a comment for 'default' case in damon_va_apply_scheme()
The switch case 'DAMOS_STAT' and switch case 'default' have same return
value in damon_va_apply_scheme(), and the 'default' case is for DAMOS
actions that not supported by 'vaddr'. It might make sense to add a
comment here.
