Tony Lindgren 6be1a8d50b serial: core: Fix kmemleak issue for serial core device remove 
Kmemleak reports issues for serial8250 ports after the hardware specific
driver takes over on boot as noted by Tomi.

The kerneldoc for device_initialize() says we must call device_put()
after calling device_initialize(). We are calling device_put() on the
error path, but are missing it from the device remove path. This causes
release() to never get called for the devices on remove.

Let's add the missing put_device() calls for both serial ctrl and
port devices.

Fixes: 84a9582fd2 ("serial: core: Start managing serial controllers to enable runtime PM")
