Warn if we skipped all blocks while writing

Quick hack to print a warning if we skip all blocks in a write
process because they are already equal to the requested image. We
want something like this to make users aware... and some developers
who regularly fall for this too *coughcough*. There might be more
elegant solutions for this... patches welcome.

This does not work for erasing because we do that unconditionally.

Corresponding to flashrom svn r1680.
