PCI: endpoint: Clear secondary (not primary) EPC in pci_epc_remove_epf()
In addition to a primary endpoint controller, an endpoint function may be
associated with a secondary endpoint controller, epf->sec_epc, to provide
NTB (non-transparent bridge) functionality.
Previously, pci_epc_remove_epf() incorrectly cleared epf->epc instead of
epf->sec_epc when removing from the secondary endpoint controller.
Extend the epc->list_lock coverage and clear either epf->epc or
epf->sec_epc as indicated.
