The of_find_device_by_node() takes a reference to the underlying device

Detected by coccinelle with the following ERROR:
./arch/sparc/include/asm/floppy_64.h:595:3-9: ERROR: missing put_device;
call of_find_device_by_node on line 589, but without a corresponding
object release within this function.
