SUNRPC: simplify auth_unix.
1/ discard 'struct unx_cred'. We don't need any data that is not already in 'struct rpc_cred'. 2/ Don't keep these creds in a hash table. When a credential is needed, simply allocate it. When not needed, discard it. This can easily be faster than performing a lookup on a shared hash table. As the lookup can happen during write-out, use a mempool to ensure forward progress. This means that we cannot compare two credentials for equality by comparing the pointers, but we never do that anyway.
