Explicitly set current values before drawing

dEQP-GLES3.functional.vertex_array_objects.all_attributes was relying on
the value of disabled integer attributes. This behavior results in
undefined values, as the initial values for all vertex attributes are of
floating-point type.

Affects:

dEQP-GLES3.functional.vertex_array_objects.all_attributes

Components: AOSP
