Summary
wifi: rtw89: fix potential race condition between napi_init and napi_enable
Details

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

wifi: rtw89: fix potential race condition between napiinit and napienable

A race condition can happen if netdev is registered, but NAPI isn't initialized yet, and meanwhile user space starts the netdev that will enable NAPI. Then, it hits BUG_ON():

To fix this, follow Jonas' suggestion to switch the order of these functions and move register netdev to be the last step of PCI probe. Also, correct the error handling of rtw89coreregister_hw().
