Fixed buffer offset when primitive restart is enabled
The data pointer 'buffer->data()' was being used without the
offset applied, which means we were using the wrong part of
the index buffer when primitive restart is enabled. 'indices'
should already contain the properly offset buffer pointer,
so using it directly should work.
