[PATCH 14/16] lguest: support v1 endian for per-device config.

[Rusty Russell <rusty@au1.ibm.com>]

From: Rusty Russell <rusty@rustcorp.com.au>

We only use the config space for the block device (we can use the net device,
but the mac address is endian-neutral).

For some inexplicable reason, this previously used le conversion macros.
