cproudlock 25f65424c7 blancco-init: load xhci_pci so USB-C NICs work, report why a link fails ...

The initrd has no udev, so only modules init names get loaded, and
xhci_pci is a module in the Ubuntu kernel. USB 3 / USB-C ports were
therefore dead in the UEFI Blancco path and a Dell USB-C to RJ45 adapter
never appeared; init took the onboard e1000e port with no cable.

- modprobe xhci_pci and xhci_pci_renesas before the NIC drivers
- bring up interfaces inside the carrier wait too, since USB NICs
  enumerate seconds after onboard ports
- on no-link, print each interface's driver and the NIC/firmware/link
  kernel messages before dropping to a shell

Live kexec-initrd.img also now carries the NIC firmware set from the
Blancco 7.20 early cpio (rtl_nic, tigon, bnx2x, ...) under /lib/firmware.
The playbook build does not add it yet.
