Location changing - blocking

For devices with assigned Asset (only without is_blade flag) there are no more possibility to change position.
I'd rather go with something like that (more or less :wink:):

There's one more restriction here - when a device is assigned to an asset (without ``is_blade`` flag), you can not change its position fields (i.e. parent, dc, rack, position, orientation). In order to do that, you should use "Assets" module instead. This should be considered as a temporary workaround, because in the future, position will be stored only in the "Assets" module.
