wcn36xx: 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 wcn36xx_hal_ind_msg {
struct list_head list;
size_t msg_len;
u8 msg[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
