Fix pci_add storage not to exit on bad first argument
Monitor command "pci_add ADDR storage ..." does its work in
qemu_pci_hot_add_nic(). It called pci_create(..., ADDR) to create the
device. That's wrong, because pci_create() terminates the program
when ADDR is invalid.
Use pci_get_bus_devfn() and pci_create_noinit() instead.
