[PATCH] sparc: kernel: add missing put_device()

[sunran001]

The of_find_device_by_node() takes a reference to the underlying device
structure, we should release that reference.

Detected by coccinelle with the following ERRORS:
./arch/sparc/kernel/pci_psycho.c:308:2-8: ERROR: missing put_device;
call of_find_device_by_node on line 290, but without a corresponding
object release within this function.
./arch/sparc/kernel/pci_psycho.c:350:0-1: ERROR: missing put_device;
call of_find_device_by_node on line 290, but without a corresponding
object release within this function.
