[Mesa-dev] [PATCH] glsl: fix compiler warnings in link_uniforms.cpp

[Brian Paul]

With a non-debug build, gcc has two complaints:
1. 'found' var not used.  Silence with '(void) found;'
2. 'id' not initialized.  It's assigned by the UniformHash->get()
   call, actually.  But init it to zero to silence gcc.
