PCI/IOV: Fix memory leak in pci_iov_add_virtfn()
In the implementation of pci_iov_add_virtfn() the allocated virtfn is
leaked if pci_setup_device() fails. The error handling is not calling
pci_stop_and_remove_bus_device(). Change the goto label to failed2.
Fixes: 156c55325d30 ("PCI: Check for pci_setup_device() failure in pci_iov_add_virtfn()")
