mesa: avoid segfault in GetProgramPipelineInfoLog when no length

Browse source 
If there is no pipe info log, we would unconditionally deref length,
which was only optionally there. _mesa_copy_string handles the source
being null, as well as the length, so may as well just always call it.

Fixes a segfault in

dEQP-GLES31.functional.state_query.program_pipeline.info_log
