UBI fastmap updates

[Richard Weinberger]

this series is a collection of all pending UBI fastmap updates.

Richard Genoud found issues in combination with U-Boot.
These issues also uncovered other minor issues in some error paths.
Only one fix is not really fastmap specific and touches generic 
UBI code, "UBI: simplify image sequence test".

Thanks,
//richard
