i3c: master: 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 the following form: sizeof(*defslvs) + ((ndevs - 1) * sizeof(struct i3c_ccc_dev_desc)) with: struct_size(defslvs, slaves, ndevs - 1) This code was detected with the help of Coccinelle.
