perf/x86/intel/lbr: Kill off intel_pmu_needs_lbr_smpl for good
The x86_lbr_exclusive commit (4807034248be "perf/x86: Mark Intel PT and
LBR/BTS as mutually exclusive") mistakenly moved intel_pmu_needs_lbr_smpl()
to perf_event.h, while another commit (a46a2300019 "perf: Simplify the
branch stack check") removed it in favor of needs_branch_stack().
This patch gets rid of intel_pmu_needs_lbr_smpl() for good.
