[PATCH] fetch2: Display all missing checksum at once

[frederic.martinsons@gmail.com]

From: Frederic Martinsons <frederic.martinsons@gmail.com>

Instead of only display the first and stop.
For recipe (crago based) that can contains several artifacts
to fetch with their checksum, it will particularly handy
to display all of missing one.

An example of error message would be
