remoteproc: k3: Call of_node_put(rmem_np) only once in three functions

An of_node_put(rmem_np) call was immediately used after a pointer check
for a of_reserved_mem_lookup() call in three function implementations.
Thus call such a function only once instead directly before the checks.

This issue was transformed by using the Coccinelle software.
