delay_pools.c is buggy in 2.3.STABLE3 :-(

Was reading through the code in 2.3.STABLE3, it's buggy. It will cause
no traffic to be allocated for host/net 255 in Class3 - Class2 is OK
(and is as I remember coding things... I thought I did them both that
way).

The relevant routines are delayUpdateClass2 and delayUpdateClass3.
Since the "for" loop conditions right above the assert()s guarantee
the assert()s I've removed them from that routine only in the below
patch.

(even though I think they're all a waste :) ... I've only taken out
the 3 extremely obviously never possibly broken ones)
