node_shader_utils: Proper fix for node_normalmap accessor returning ellipsis value.

Browse Source 
Ellipsis value is internal ingredient only, to tag hidden _node_normalmap
'real' property as not yet initialized. Public node_normalmap accessor
should never ever have that value, it's either None or a valid node!
