[PATCH 3/5] powerpc/perf: Replace last usage of get_cpu_var with this_cpu_ptr

[Anshuman Khandual <khandual@linux.vnet.ibm.com>]

The commit 69111bac42f5ce ("powerpc: Replace __get_cpu_var uses")
replaced all usage of get_cpu_var with this_cpu_ptr inside core
perf event handling on powerpc. But it skipped one of them which
is being replaced with this patch.
