[PATCH] knfsd: make sure svc_process call the correct pg_authenticate for multi-service port

Browse Source 
If an RPC socket is serving multiple programs, then the pg_authenticate of
the first program in the list is called, instead of pg_authenticate for the
program to be run.

This does not cause a problem with any programs in the current kernel, but
could confuse future code.

Also set pg_authenticate for nfsd_acl_program incase it ever gets used.
