From: Frank Rowand <frank.rowand@xxxxxxxx>
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: 39a751a4cb7e ("of: change overlay apply input data from unflattened to FDT")
