No explicit error message when VTK surfaces are requested without airfoil coordinates

[ebranlard]

Bug description
OpenFAST aborts with no explicit error message when VTK surfaces are requested without airfoil coordinates being provided in airfoil files.

To Reproduce
Set VTK_type=1 and WrVTK=1 for a simulation where no airfoil coordinates are provided in all or one of the airfoil files.

Expected behavior
Explicit error message provided.

Hmmm... I get the error message "Cannot do surface visualization without airfoil coordinates defined in AeroDyn" (this is running the code from #373) :

It might be due to some warning message that took priority or filled the error message buffer. Here's what I get (with the version from #373):

Yes, it looks like the error message just got too large for this model with all those mesh-mapping messages. I put a little work-around in my linearization pull request to print informational messages a bit early so that error messages after the mesh-mapping informational messages get printed, too.

Thanks that does the trick!
