NSX: restriction on distributed update must be lifted

[Salvatore Orlando]

The NSX backend from version 4.1 does not have anymore any restriction on transformation of centralized routers in distributed.
Version 3.x instead could not transform distributed routers into centralized, which is anyway consistent with the current DVR extension.

The current restriction specific for the NSX plugin must therefore be lifted.

    NSX: lift restriction on DVR update

    The restriction in place in the code is not justified considered
    the capabilities of the DVR extension and the NSX backend.

    Transformations of centralized routers into distributed should be
    allowed.
