perf/x86/intel/pt: Fix the 32-bit build

Browse Source 
On a 32-bit build I got:

  arch/x86/kernel/cpu/perf_event_intel_pt.c:413:5: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
  arch/x86/kernel/cpu/perf_event_intel_bts.c:162:24: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

Fix it. The code should probably be (re-)tested on 32-bit systems to make
sure all is fine.
