Fix LVM migrate_volume tests
Fix LVM migrate_volume tests

In cinder/tests/test_volume.py the following tests fail to correctly
test the functionality.

LVMISCSIVolumeDriverTestCase.test_lvm_migrate_volume_diff_driver
LVMISCSIVolumeDriverTestCase.test_lvm_migrate_volume_diff_host

The location_info is incorrect, it needs to be 5 sections separated by
colons otherwise they fail due to bad location info.
