The cdnsp-pci driver uses pcim_enable_device() to enable a PCI device,
which means the device will be automatically disabled on driver detach
through the managed device framework. The manual pci_disable_device()
call in the error path is therefore redundant.

Found via static anlaysis and this is similar to commit 99ca0b57e49f
("thermal: intel: int340x: processor: Fix warning during module unload").

Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver")
