Comment clarifying a libmesh_error()

I'm choosing to make the SerialMesh behavior less robust here in order
to catch inefficient SerialMesh usage even when that usage isn't
technically incorrect.  We might want to make the error test more
complicated and change this error to a debug-mode warning in the
future.
