[PATCH] fix: drivers/usb/cdns3: cdnsp_pci_probe: missing pci_dev_put for func on success path

[WenTao Liang]

In cdnsp_pci_probe(), cdnsp_get_second_fun() acquires a reference on func
via pci_get_device(). All error paths correctly jump to put_pci label
which calls pci_dev_put(func). However, the success path returns 0
directly without releasing the func reference, leaking it.

Add pci_dev_put(func) before returning 0 on the success path.
