isisd: remove useless checks when configuring ldp-sync

Browse Source 
We have checks on NB validation stage to prevent configuring LDP sync on
interfaces in non-default VRFs. These checks are completely useless,
because the interface can be easily moved to another VRF after
configuring LDP sync. Instead, the check must be done in the actual code
to cover the case when the interface is moved between VRFs.
