r600: index_bias should be forced to zero for all indirect draw calls

Browse Source 
The previous fix 0cae8d372e is the right way to proceed, but it
should also apply when index_size is non-zero.

This change was tested on palm and cayman. Here is the test fixed:
spec/arb_multi_draw_indirect/arb_draw_elements_base_vertex-multidrawelements -indirect: fail pass

Fixes: 0cae8d372e ("r600: don't set an index_bias for indirect draw calls")
