drm/nouveau/mmu: 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(*kind) + sizeof(*kind->data) * mmu->kind_nr;
with:
struct_size(kind, data, mmu->kind_nr)
This code was detected with the help of Coccinelle.
