Drawing without current program is not an error.

The spec states that "If UseProgram is called with program set to zero,
then there is no current program object, and the results of vertex and
fragment shader execution are undefined. However, this is not an
error."

Fixes all failures in:
dEQP-GLES3.functional.negative_api.vertex_array.*
