xen/pcifront: Process failure for pcifront_(re)scan_root()
When pcifront_try_connect() finds no PCI roots, it falls back to calling
pcifront_scan_root() for 0000:00. If that fails, it used to switch to
XenbusStateConnected and return success (because xenbus_switch_state()
currently always succeeds).
If pcifront_scan_root() fails, leave the XenbusState unchanged and return
an error code.
Similarly, pcifront_attach_devices() falls back to calling
pcifront_rescan_root() for 0000:00. If that fails, it used to switch to
XenbusStateConnected and return an error code.
If pcifront_rescan_root() fails, leave the XenbusState unchanged and return
the error code.
