qemu-iotests: Use zero-based offsets for IO patterns

The io_pattern style functions have the following loop:

for i in `seq 1 $count`; do
      echo ... $(( start + i * step )) ...
  done

Offsets are 1-based so start=1024, step=512, count=4 yields:

Some image formats support backing images that are smaller than the
image file. This patch adds a test that verifies that reads and writes
beyond the end of backing image work.

Unallocated reads beyond the end of the backing file should produce...
