SUNRPC/nfs: Fix return value for nfs4_callback_compound()

Browse Source 
RPC server procedures are normally expected to return a __be32 encoded
status value of type 'enum rpc_accept_stat', however at least one function
wants to return an authentication status of type 'enum rpc_auth_stat'
in the case where authentication fails.
This patch adds functionality to allow this.

Fixes: a4e187d83d ("NFS: Don't drop CB requests with invalid principals")
