libxl: Rename libxl__device_nic_from_xs_be to _from_xenstore

We are going to change these functions to expect, and be passed, a
/libxl path.  So it is wrong that they are called _from_xs_be.

Neither function reads anything which isn't found in both places, so
we can and will change the call sites later.

The only remaining function in libxl called *_from_xs_be relates to
PCI devices, for which the backend domain is hardcoded to 0 throughout
the libxl_pci.c.

No functional change.

This is part of XSA-178.
