    x86/topology: Remove x86_smt_flags and use cpu_smt_flags directly

    x86_*_flags() wrappers were introduced with commit d3d37d8
    ("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 995998e ("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.
