fsl/fman: Fix missing put_device() call in fman_port_probe
[ Upstream commit bf2b09fedc17248b315f80fb249087b7d28a69a6 ]
The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the and error handling paths.
Fixes: 18a6c85fcc78 ("fsl/fman: Add FMan Port Support")
