Christian A. Ehrhardt b9d760dae5 of: Fix double free in of_parse_phandle_with_args_map 
[ Upstream commit 4dde835698 ]

In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.

Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".

Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

Fixes: bd6f2fd5a1 ("of: Support parsing phandle argument lists through a nexus node")
