    nfsd: correctly handle return value from nfsd_map_name_to_*
    
    These functions return an nfs status, not a host_err.  So don't
    try to convert  before returning.
    
    This is a regression introduced by
    3c726023402a2f3b28f49b9d90ebf9e71151157d; I fixed up two of the callers,
    but missed these two.
