Remove NULL checks of function pointers from struct rtllib_device. This checks are unnecessary because the function pointers are set right when the driver is loaded. Here the flow when function pointers are set: .probe = _rtl92e_pci_probe In _rtl92e_pci_probe the function _rtl92e_init is called. In the second line of _rtl92e_init is _rtl92e_init_priv_handler called that sets all the required function calls.
