Fix negative zio->io_error which must be positive.
All the upper layers of zfs expect zio->io_error to be positive. I was careful but I missed one instance in vdev_disk_physio_completion() which could return a negative error. To ensure all cases are always caught I had additionally added an ASSERT() to check this before zio_interpret(). Finally, as a debugging aid when zfs is build with --enable-debug all errors from the backing block devices will be reported to the console with an error message like this: ZFS: zio error=5 type=1 offset=4217856 size=8192 flags=60440
