mm/page_owner: use scnprintf() to avoid excessive buffer overrun check

The snprintf() function can return a length greater than the given input
size.  That will require a check for buffer overrun after each
invocation of snprintf().  scnprintf(), on the other hand, will never
return a greater length.

By using scnprintf() in selected places, we can avoid some buffer
overrun checks except after stack_depot_snprint() and after the last
snprintf().
