[libvirt PATCH] Revert "Also look for dmi information in /sys/class"

[Ján Tomko <jtomko@xxxxxxxxxx>]

Assume nobody runs current libvirt on kernels such as 2.6.26.

Kernel commit 9f9c9cbb60576a1518d0bf93fb8e499cffccf377 (released
in 3.8) mentions the new path and I believe it was added by:
commit 948af1f0bbc8526448e8cbe3f8d3bf211bdf5181
    firmware: Basic dmi-sysfs support
(released in 2.6.39), but I cannot figure out how all that
kernel automagic works.

This reverts commit 4c81b0fdc57b23d80b1b4752cd6143d15c02e9c8
