[PATCH] fsl/fman: Fix fm_pdev reference leak in fman_port_probe()

[Wentao Liang]

of_find_device_by_node() takes a reference on the FMan device. It is
released on the error paths, but the successful path returns without
dropping it, leaking the reference.

Release the reference when it is not needed anymore.
