This reverts commit d92f150f9cb80b4df56331d1f42442da78e351f0.
It seems send_packet() is used during initialization, before send_packet_delay is set.
This will be fixed by another patch.
Reverting patches is a resource that we generally use only when
there's something deadly wrong, as it makes the git history
dirtier, hides the reasons why a change is needed, and might be bad
for git bisecting.
In this specific case, by applying both the revert patch and your newer
one, it is clear that your intent is to move the logic that changes
the send packet delay, because it needs to happen earlier.
So, instead of applying both patches, I'll fold them into one,
as enclosed.

send_packet() is used during initialization, before send_packet_delay
is set. So, move ictx->send_packet_delay to happen earlier.
