vbo: ignore primitive restart if FixedIndex is enabled in DrawArrays
From GL 4.4 Core profile:
If both PRIMITIVE_RESTART and PRIMITIVE_RESTART_FIXED_INDEX are
enabled, the index value determined by PRIMITIVE_RESTART_FIXED_INDEX is
used. If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not
performed for array elements transferred by any drawing command not taking a
type parameter, including all of the *Draw* commands other than *DrawEle-
ments*.
