of: unittest: fix memory leak in unittest_data_add
[ Upstream commit e13de8fe0d6a51341671bbe384826d527afe8d44 ]
In unittest_data_add, a copy buffer is created via kmemdup. This buffer
is leaked if of_fdt_unflatten_tree fails. The release for the
unittest_data buffer is added.
Fixes: b951f9dc7f25 ("Enabling OF selftest to run without machine's devicetree")
