Commit Message

sd-dhcp-relay: fix off-by-one when discarding BOOTREQUEST messages by hops count

According to RFC specifications
```
RFC 1542 section 4.1.1 states:
The relay agent MUST silently discard BOOTREQUEST messages whose 'hops'
   field exceeds the value 16."
```

"Exceeds the value 16" means hops > 16, i.e. a message that arrives with
hops == 16 is still valid and must be relayed (after which its hops field
becomes 17). The code used ">= 16", which silently dropped a valid message
that had legitimately traversed exactly 16 relay agents, one hop too early.

This matches the wording of the adjacent comment, which already says
"exceeds the value 16".
