Fix: extend in-use volumes check

Browse Source 
Currently we have 2 issues with extending volumes checks:

1. We don't specify explicitly that MV 3.42 needs to be passed for
in-use volumes
2. Any state of volume (error, attaching, detaching etc) can pass
this check by specifying MV 3.42

The fundamentally correct approach to these checks should be:

1. Only allow 'available' and 'in-use' volumes to be extended
2. Check MV 3.42 or greater is specified in case of 'in-use' volumes
otherwise fail

This approach is implemented in the patch.
