Kunihiko Hayashi f58d5f53c8 PCI: endpoint: Fix clearing start entry in configfs ... After an endpoint is started through configfs, if 0 is written to the configfs entry 'start', the controller stops but the epc_group->start value remains 1. A subsequent unlinking of the function from the controller would trigger a spurious WARN_ON_ONCE() in pci_epc_epf_unlink() despite right behavior. Fix it by setting epc_group->start = 0 when a controller is stopped using configfs.
