Fixing some logic issues with the aws-instance resource

1. The schema contained a few fields that where not marked as
`computed`, while they were updated inside the resource.

2. While updating the `volume_size` it was doing so with a `string`,
but in the schema this field is set as `int`.

3. The set func for calculating the hashes for the `block` set items,
also used computed values to calculate the hash. As these values will
not be in the config, but only in the state, this will always show as a
diff. The solution is to only use the fields that aren’t computed in
order to get consistent hashes.

These where all issues before, but weren’t visible as such. All should
be good again now.

Fixing aws_instance schema

Some instance types have a block device by default. So when selecting
such an instance type, you will not set a config for the block device,
but the update/refresh func will notice one and update the state
nonetheless.

So in those cases the `block_device` becomes a `computed` field.

Fixing aws_elb schema

If not suppling the `availability_zones`, they will be computed
(meaning an update/refresh will retrieve the info and update the values
to the state file).

So without the `Computed = true` the diff will always flag this as a
change, even when it’s not.
