ubiformat: handle write errors correctly
This issue was reported and analyzed by Anton Olofsson <anol.martinsson@gmail.com>: when ubiformat encounters a write error while flashing the UBI image (which may come from a file of from stdout), it correctly marks the faulty eraseblock as bad and skips it. However, it also incorrectly drops the data buffer which was supposed to be written, and reads next block of data. This patch fixes this issue - in case of a write error, we preserve the current data and write it to the next eraseblock, instead of dropping it.
