ksmbd: return STATUS_OBJECT_NAME_NOT_FOUND for unknown IPC pipe names

Browse source

create_smb2_pipe() maps ksmbd_session_rpc_open() failing with -EINVAL
(pipe name not recognized/supported) to STATUS_INVALID_PARAMETER.
macOS Time Machine's backupd treats STATUS_INVALID_PARAMETER on a
pipe open as a fatal error and aborts the backup immediately, whereas
STATUS_OBJECT_NAME_NOT_FOUND is handled gracefully -- the client just
treats that particular pipe as unavailable and continues.
