A coccicheck run provided information like the following.

arch/arm/mach-imx/pm-imx6.c:586:1-7: ERROR: missing put_device;
call of_find_device_by_node on line 485, but without a corresponding
object release within this function.

Generated by: scripts/coccinelle/free/put_device.cocci

Thus adjust jump targets to fix the exception handling for this
function implementation.

Fixes: df595746fa69db2e36d89677df26ba51f9706c1b ("ARM: imx: add suspend in ocram support for i.mx6q")
