sched/fair: Fix scale_rt_capacity() for SMT

Since commit:

  523e979d3164 ("sched/core: Use PELT for scale_rt_capacity()")

scale_rt_capacity() returns the remaining capacity and not a scale factor
to apply on cpu_capacity_orig. arch_scale_cpu() is directly called by
scale_rt_capacity() so we must take the sched_domain argument.
