drm/nouveau: fix nvkm_device leak on aperture removal failure

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: fix nvkm_device leak on aperture removal failure

When aperture_remove_conflicting_pci_devices() fails during probe, the
error path returns directly without unwinding the nvkm_device that was
just allocated by nvkm_device_pci_new(). This leaks both the device
wrapper and the pci_enable_device() reference taken inside it.

Jump to the existing fail_nvkm label so nvkm_device_del() runs and
balances both. The leak was introduced when the intermediate
nvkm_device_del() between detection and aperture removal was dropped
in favor of creating the pci device once.
