of: unittest: kmemleak in of_unittest_overlay_high_level()

Browse Source 
kmemleak reports several memory leaks from devicetree unittest.
This is the fix for problem 3 of 5.

of_unittest_overlay_high_level() failed to kfree the newly created
property when the property named 'name' is skipped.

Fixes: 39a751a4cb ("of: change overlay apply input data from unflattened to FDT")
