iwlwifi: dvm: use struct_size over open coded arithmetic
Replace zero-length array with flexible-array member and make use
of the struct_size() helper in kmalloc(). For example:
struct iwl_wipan_noa_data {
...
u8 data[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
