of/unittest: Swap arguments of of_unittest_apply_overlay()

Function signature

  of_unittest_apply_overlay(int unittest_nr, int overlay_nr, ...

and call sites, like in of_unittest_apply_overlay_check():

  ret = of_unittest_apply_overlay(overlay_nr, unittest_nr, ...

do not match. Fix this in one place (function signature).
The only affected test case is 15, which supplies non-existing
overlay number 16, but two bugs matched here. Fix the test case.
