[PATCH 3/3] ubi: Fix Fastmap's update_vol()

[Richard Weinberger]

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.
