openrisc: Fix a memory leak
[ Upstream commit c019d92457826bb7b2091c86f36adb5de08405f9 ]
'setup_find_cpu_node()' take a reference on the node it returns.
This reference must be decremented when not needed anymore, or there will
be a leak.
Add the missing 'of_node_put(cpu)'.
Note that 'setup_cpuinfo()' that also calls this function already has a
correct 'of_node_put(cpu)' at its end.
Fixes: 9d02a4283e9c ("OpenRISC: Boot code")
