Yang Yingliang 02cd3032b1 cxl: fix possible null-ptr-deref in cxl_pci_init_afu|adapter()
If device_register() fails in cxl_pci_afu|adapter(), the device
is not added, device_unregister() can not be called in the error
path, otherwise it will cause a null-ptr-deref because of removing
not added device.

As comment of device_register() says, it should use put_device() to give
up the reference in the error path. So split device_unregister() into
device_del() and put_device(), then goes to put dev when register fails.

Fixes: f204e0b8ce ("cxl: Driver code for powernv PCIe based cards for userspace access")
