cpufreq: qcom-nvmem: fix memory leaks in probe error paths

[ Upstream commit d01c84b9 ]

The code refactoring added new error paths between the np device node
allocation and the call to of_node_put(), which leads to memory leaks if
any of those errors occur.

Add the missing of_node_put() in the error paths that require it.
