For R1 AckAll consumers with Interest/WorkQueue retention would set the floor to sgap, which is the amount of messages that need to be deleted. However, that's incorrect, for example with:

o.asflr = 2500
sseq = 2550
sgap = 50

We would scan from 2550 to 50, instead of from 2550 to 2501. If the FirstSeq of the stream was already at 2501, then we'd be doing over 2k additional iterations of mset.ackMsg.

for seq := sseq; seq >= floor; seq-- {
	mset.ackMsg(o, seq)
}
