remoteproc: qcom: Fix missing of_node_put in adsp_alloc_memory_region

BugLink: https://bugs.launchpad.net/bugs/1971497
[ Upstream commit 505b5b1616e200042999de715dbe7c1e2735cd65 ]

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