Wu Zhou 925e3d95b4 hv: add max_len for sbuf_put param ... sbuf_put copies sbuf->ele_size of data, and puts into ring. Currently this function assumes that data size from caller is no less than sbuf->ele_size. But as sbuf->ele_size is usually setup by some sources outside of the HV (e.g., the service VM), it is not meant to be trusted. So caller should provide the max length of the data for safety reason. sbuf_put() will return UINT32_MAX if max_len of data is less than element size. Additionally, a helper function sbuf_put_many() is added for putting multiple entries.
