x86/topology: Remove x86_smt_flags and use cpu_smt_flags directly

Browse Source 
x86_*_flags() wrappers were introduced with commit d3d37d850d
("x86/sched: Add SD_ASYM_PACKING flags to x86 ITMT CPU") to add
x86_sched_itmt_flags() in addition to the default domain flags for SMT
and MC domain.

commit 995998ebde ("x86/sched: Remove SD_ASYM_PACKING from the
SMT domain flags") removed the ITMT flags for SMT domain but not the
x86_smt_flags() wrappers which directly returns cpu_smt_flags().

Remove x86_smt_flags() and directly use cpu_smt_flags() to derive the
flags for SMT domain. No functional changes intended.
