vulkan/pipeline_cache: replace raw data objects on cache insertion of real 
objects

It might happen that a raw data object (from pipeline cache creation)
was never looked up, and thus never deserialized, before it gets
inserted again into the cache. In this case, the deserialized object
got replaced by the raw data object.
Instead, replace the raw data object with the real object in the cache.

Fixes: 8b13ee75ba9f27ceac6b6180ca05d321caa13612 ('vulkan: Fall back to raw data 
objects when deserializing if ops == NULL')
