[PATCH] lib: fwts_virt: fix non-Intel build errors

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

This fixes a -Wextra build error for non-Intel builds.  This function
is only used in x86 tests so we can just make this function return dummy
values anyway since it is never called on non-x86 systems.
