dediprog: Fix small, unaligned reads

This never was a use case until now but the `--fmap` code makes it
obvious: Unaligned reads that were smaller than the `chunksize` here,
were extended without considering the length of the buffer read into.

With that fixed we run into the next problem: dediprog_spi_bulk_read()
shouldn't report an error when an empty read is unaligned.
