clk: fix an OF node reference leak in of_clk_get_parent_name()
[ Upstream commit 28fa3291cad1c201967ef93edc6e7f8ccc9afbc0 ]
Current implementation of of_clk_get_parent_name() leaks an OF node
reference on error path. Add a of_node_put() call before returning an
error.
This bug was found by an experimental static analysis tool that I am
developing.
