gallium/util: Break recursion in pipe_resource_reference

It calling itself recursively prevented it from being inlined, resulting
in a copy being generated in every compilation unit referencing it. This
bloated the text segment of the Gallium mega-driver *_dri.so by ~4%,
and might also have impacted performance.

Fixes: ecd6fce2611e ("mesa/st: support lowering multi-planar YUV")
v2:
* Add comment above pipe_resource_next_reference [Samuel Pitoiset]
v3:
* Use loop to unreference the full chain of resources referenced via
  the next members [Timothy Arceri]
v4:
* Stop chasing ->next chain at the first sub-resource which isn't
  destroyed [Nicolai Hähnle]
