Subject: [PATCH] UBI: improve corrupted flash handling

This patch improves the way UBI handles corrupted flash, or flash
containing garbage or non-UBI data, which is the same from UBI POW.
Namely, we do the following:

* if 5% or more PEBs are corrupted, refuse the flash
* if less than 5% PEBs are corrupted, do not refuse the flash
  and format these PEBs
* if less than 8 PEBs are corrupted, format them silently, otherwise
  print a warning message.
