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.
Fixes: d74679911610 ("PCI: endpoint: Introduce configfs entry for configuring EP functions")
