mesa: fix _mesa_free_pipeline_data() use-after-free bug

Unreference the ctx->_Shader object before we delete all the pipeline
objects in the hash table.  Before, ctx->_Shader could point to freed
memory when _mesa_reference_pipeline_object(ctx, &ctx->_Shader, NULL)
was called.

Fixes crash when exiting the piglit rendezvous_by_location test on
Windows.
