vz: fix cleanup of nets of bridged type

We create a virtual network of special type, which
has the same name as bridge name to create bridged
network adapter in vz. So when we delete such an
adapter we have to remove corresponding virtual
network.

So let's rename prlsdkDelNet to prlsdkCleanupBridgedNet
and don't check for return value.
