[PATCH 5.16 0681/1017] remoteproc: qcom_wcnss: Add missing of_node_put() in wcnss_alloc_memory_region

[ Upstream commit 8f90161a66bc3d6b9fe8dde4d9028d20eae1b62a ]

The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.

Fixes: aed361adca9f ("remoteproc: qcom: Introduce WCNSS peripheral image loader")
