PCI: endpoint: Finish virtual EP removal in pci_epf_remove_vepf()
commit 3b9f942eb21c92041905e3943a8d5177c9a9d89d upstream.
When removing a virtual Endpoint, pci_epf_remove_vepf() failed to clear
epf_vf->epf_pf, which caused a subsequent pci_epf_add_vepf() to incorrectly
return -EBUSY:
pci_epf_add_vepf(epf_pf, epf_vf) // add
pci_epf_remove_vepf(epf_pf, epf_vf) // remove
pci_epf_add_vepf(epf_pf, epf_vf) // add again, -EBUSY error
Fix by clearing epf_vf->epf_pf in pci_epf_remove_vepf().
