ubi: Fix Fastmap's update_vol()
commit f7d11b33d4e8cedf19367c09b891bbc705163976 upstream.
Usually Fastmap is free to consider every PEB in one of the pools
as newer than the existing PEB. Since PEBs in a pool are by definition
newer than everything else.
But update_vol() missed the case that a pool can contain more than
one candidate.
