EX-8189 osc: do not compress resends

There's some issue with doing compression on resent
requests, so this patch works around it with two things:
1. Use the uncompressed page array for resend
(this was always necessary unless we modified resend to
know it already had compressed pages as input)
2. Disable compression on resend (not clear why 1. wasn't
enough)
