UBUNTU: SAUCE: x86/cacheinfo: Clean out init_cache_level()

BugLink: https://bugs.launchpad.net/bugs/2049793

init_cache_level() no longer has a purpose on x86. It no longer needs to
set num_leaves, and it never had to set num_levels, which was unnecessary
on x86.

Replace it with "return 0" simply to override the weak function, which
would return an error.
