mm/damon/sysfs: do not directly access damon_ctx->ops

Browse Source 
damon_ctx->ops field is intended to be used by only the DAMON core layer. 
DAMON_SYSFS is directly reading the field to find if it is for physical
address monitoring, though.  Use the API function for the purpose,
damon_target_has_pid(), instead.
