tests: support zero_dev
When the test would need to try to write some large amount of data
we can give it 'zero' segments - for obvious reason such written data
can't be verified but in some test cases it doesn't really matter.
Usage follows 'error_dev' style.
For now test suite is not supporting any combination of
error/delay/zero segments so only 1 type could be used per PV.
