iwlwifi: lib: 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, change the following form: sizeof(*pattern_cmd) + wowlan->n_patterns * sizeof(struct iwlagn_wowlan_pattern) to : struct_size(pattern_cmd, patterns, wowlan->n_patterns) This code was detected with the help of Coccinelle.
