x86: clean up and fix setup_clear/force_cpu_cap handling
setup_force_cpu_cap() only have one user (Xen guest code),
but it should not reuse cleared_cpu_cpus, otherwise it
will have problems on SMP.
Need to have a separate cpu_cpus_set array too, for forced-on
flags, beyond the forced-off flags.
Also need to setup handling before all cpus caps are combined.
[ Impact: fix the forced-set CPU feature flag logic ]
