i965: Allow disk shader cache usage with LINKING_SUCCESS status
Currently, we only look in the disk shader cache if we see that the shader program is in the cache during the link step. If the shader cache entry isn't found during the program link, there are still some (fairly unlikely) scenarios where later it might be useful to search the cache for gen binary programs. 1. If the cache evicts the serialized glsl cache, there might still be valid gen program entries in the disk cache. 2. If two applications are running in parallel, then it is possible that one may write out the cached gen program item which the other application can then make use of.
