perf_counter: powerpc: Fix two compile warnings

Browse source 
This fixes a couple of compile warnings that crept into the powerpc
perf_counter code recently:

   CC      arch/powerpc/kernel/perf_counter.o
 arch/powerpc/kernel/perf_counter.c: In function 'record_and_restart':
 arch/powerpc/kernel/perf_counter.c:1016: warning: unused variable 'addr'
 arch/powerpc/kernel/perf_counter.c: In function 'hw_perf_counter_init':
 arch/powerpc/kernel/perf_counter.c:891: warning: 'ev' may be used uninitialized in this function

Stephen Rothwell reported this against linux-next as well.
