perf_counter, powerpc, sparc: Fix compilation after perf_counter_overflow() change

Commit 5622f295 ("x86, perf_counter, bts: Optimize BTS overflow
handling") removed the regs field from struct perf_sample_data and
added a regs parameter to perf_counter_overflow().  This breaks the
build on powerpc (and Sparc) as reported by Sachin Sant:

  arch/powerpc/kernel/perf_counter.c: In function 'record_and_restart':
  arch/powerpc/kernel/perf_counter.c:1165: error: unknown field 'regs' specified in initializer

This adjusts arch/powerpc/kernel/perf_counter.c to correspond with the
new struct perf_sample_data and perf_counter_overflow().

[ v2: also fix Sparc, Markus Metzger <markus.t.metzger@intel.com> ]
