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").
