    mesa: return initial value for VALIDATE_STATUS if pipe not bound

    From OpenGL 4.5 Core spec (7.13):

        "If pipeline is a name that has been generated (without subsequent
        deletion) by GenProgramPipelines, but refers to a program pipeline
        object that has not been previously bound, the GL first creates a
        new state vector in the same manner as when BindProgramPipeline
        creates a new program pipeline object."

    I interpret this as "If GetProgramPipelineiv gets called without a
    bound (but valid) pipeline object, the state should reflect initial
    state of a new pipeline object." This is also expected behaviour by
    ES31-CTS.sepshaderobjs.PipelineApi conformance test.
