SUNRPC: rework cache upcall logic
For most of SUNRPC caches (except NFS DNS cache) cache_detail->cache_upcall is redundant since all that it's implementations are doing is calling sunrpc_cache_pipe_upcall() with proper function address argument. Cache request function address is now stored on cache_detail structure and thus all the code can be simplified. Now, for those cache details, which doesn't have cache_upcall callback (the only one, which still has is nfs_dns_resolve_template) sunrpc_cache_pipe_upcall will be called instead.
