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.
