    nmount: Ignore errors when copying out an error string
    
    In general we copy error strings as part of reporting an error from
    lower layers, so if the copyout() fails there's nothing to do since we'd
    prefer to preserve the original error.
    
    This is in preparation for annotating copyin() and related functions
    with __result_use_check.
