[PATCH 6/9] mm/damon/dbgfs-test: skip dbgfs_set_targets() test if PADDR is not registered

The test depends on registration of DAMON_OPS_PADDR. It would be
registered only when CONFIG_DAMON_PADDR is set. DAMON core kunit tests
do fake ops registration for such case. However, the functions for such
fake ops registration is not available to DAMON debugfs interface. Just
skip the test in the case.
