[ui] [settings] Invalid setting dependency calculation

[Julia Aranovich]

Steps to reproduce:

1. create neutron-vlan env with Qemu hypervizor and go to Settings tab

2. "Install Mellanox drivers and SR-IOV plugin" option in "Mellanox drivers and SR-IOV plugin" setting is locked due to it's restriction: "settings:common.libvirt_type.value != 'kvm' or not (cluster:net_provider == 'neutron' and networking_parameters:segmentation_type == 'vlan')" - OK

3. change hypervizor to KVM, the option above becomes available, choose it - Hypervizor setting doesn't become locked due active to dependent setting!
And you can switch back to Qemu hypervizor.
So, the settings structure becomes invalid, you have Qemu and Mellanox drivers and SR-IOV plugin setting is on and locked.
