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