wifi: rtw89: fix potential race condition between napi_init and napi_enable
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: fix potential race condition between napi_init and napi_enable 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.
