In most cases we do not care about exact number of buffers linked to the header, we just need to know if it is zero, non-zero or one. That can easily be checked just looking on b_buf pointer or in some cases derefencing it. b_ebufcnt is read only once, and in that case we already traverse the list as part of arc_buf_remove(), so second traverse should not be expensive. This reduces L1 ARC header size by 8 bytes and full crypto header by 16 bytes, down to 176 and 232 bytes on FreeBSD respectively.
