[cogl-material] make _cogl_material_layer_free check for an invalid texture handle

Browse Source 
It is valid in some situations to have a material layer with an invalid texture
handle (e.g. if you setup a texture combine mode before setting the texture)
and so _cogl_material_layer_free needs to check for a valid handle before
attempting to unref it.
