I believe the goal of the check was to ensure that ip_insertoptions would
get a correctly 4-byte-aligned mbuf size, because it does not insert
padding to ensure 4-byte alignment.

If it's not aligned, ip_hl gets truncated and we probably end up sending
garbage on the network.

Alright, I've removed it.
