[PATCH] inany: Fix doc comment to match u32 field, not u64

[PATCH] inany: Fix doc comment to match u32 field, not u64

[Laurent Vivier]

The original siphash incremental patch added a u64[2] member to
union inany_addr for hashing. During review, this was changed to u32[4]
to preserve 4-byte alignment: a u64 member would have forced 8-byte
alignment on the union, mismatching struct in6_addr.

The doc comment was not updated, fix @u64 references to @u32.

Fixes: fc8f0f8c48ef ("siphash: Use incremental rather than all-at-once siphash functions")
