CLOUDSTACK-8841: Storage XenMotion from XS 6.2 to XS 6.5 fails.Removed Host version check in API. Because
Case 1:(Lower to Higher Version)
Migration from lower version to higher version is valid.
Case 2:(Higher to Lower Version)
In this case system(Host) will not allow.
So no need to check version in API. Additionally,  CLOUDSTACK User Interface(UI) does  not allow  migration between different version of hyper-visors. But sometimes user wants to do migration from  Lower to Higher Version. Now he can do it via API.
