Subject: [PATCH] mesa: Add missing call to _mesa_unlock_debug_state(ctx); v2

cd724208d3e1e3307f84a794f2c1fc83b69ccf8a added a call to
_mesa_lock_debug_state(ctx) but wasn't unlocking the debug state.

This fixes a hang in glsl-fs-loop piglit test with MESA_DEBUG=context.

v2:
  - Remove unrelated changes.
