usb: cdns3: Fix double resource release in cdns3_pci_probe

commit 1ec39d2cd8 upstream.

The driver uses pcim_enable_device() to enable the PCI device,
the device will be automatically disabled on driver detach through
the managed device framework. The manual pci_disable_device() calls
in the error paths are therefore redundant and should be removed.

Found via static anlaysis and this is similar to commit 99ca0b57e4
("thermal: intel: int340x: processor: Fix warning during module unload").
