It is possible to receive ESHUTDOWN without being disconnected. For instance, a race with suspend could cause it to happen (although if your driver is written correctly that race should never occur). Another more likely scenario is that you have an active URB while calling usb_set_interface(); the endpoints for the old altsetting get disabled and the URB returns with an ESHUTDOWN error.
