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.
