net: sched: cls_u32: 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(*s) + s->nkeys*sizeof(struct tc_u32_key) with: struct_size(s, keys, s->nkeys) This code was detected with the help of Coccinelle.
