rndis_wlan: use struct_size() helper
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace code of the following form: sizeof(*pmkids) + max_pmkids * sizeof(pmkids->bssid_info[0]) with: struct_size(pmkids, bssid_info, num_pmkids) This code was detected with the help of Coccinelle.
