Description of problem:

there is no rollback on manual reconstruct when target domain is unreachable. 
leaving us with "Wrong Master domain or its version" error

Version-Release number of selected component (if applicable):

si15

How reproducible:

100%

Steps to Reproduce:
1. create a two host cluster + 2 domains located on different storage servers (I tested on NFS)
2. from both hosts using iptables, block the non-master SD
3. put Master Stroage Domain in maintenance 
  
Actual results:

we would fail reconstruct but will not rollback 
master version will change and we would end up with "Wrong Master domain or its version" - > unable to start the old master domain. 

Expected results:

we should rollback and not change master version
