Gustavo A. R. Silva 327dd2d8e7 mlxsw: Use size_mul() in call to struct_size() 
[ Upstream commit e22c6ea025013ae447fe269269753ffec763dde5 ]

If, for any reason, the open-coded arithmetic causes a wraparound, the
protection that `struct_size()` adds against potential integer overflows
is defeated. Fix this by hardening call to `struct_size()` with `size_mul()`.
