Fix T72459: Mask Modifier breaks Vertex Parenting

The `give_parvert()` function was only considering the mesh's original
vertex indices when the parent vertex index was valid for the evaluated
mesh. However, when using the Mask modifier the evaluated mesh can have
less vertices but still have the parent vertex.

Since the `if (nr < numVertex)` condition wasn't used to prevent any
out-of-bounds access, and seems just an incorrect optimisation, it could
be removed.
