d3d11device: raise 'device-removed' signal on DXGI_ERROR_DEVICE_REMOVED

When this error gets caught the GstD3D11Device object raises the new
"device-removed" signal. This allows to handle the error from outside:
stop the playback, re-create the player, replace the catched GstContext by
the new one.
