Only flag the LayoutObject on CSP error if one is attached

Only flag the LayoutObject on CSP error if one is attached

When instantiating a plugin through the (somewhat special) code-path
that does not require a LayoutObject to be present, we would end up
dereferencing a null-pointer if a CSP error was flagged, failing the
plugin load sequence.
