i2cdump: Remove dead code

Considering that we exit immediately if an error happens during a
block read, the code filling the remaining bytes with -1 (so that
they will be displayed as "XX") is effectively dead code, so let's
remove it.

We might want to revisit the whole logic later, as there's in fact
little reason why block read errors would be fatal when all other
read errors are not. But I'd rather remove SMBus block support from
the tool before attempting to clean up the code.

Fixes: 7abc52d7792e ("Return the correct error code on I2C block read failure.")
