sparc: perf: Remove redundant perf_pmu_{en|dis}able calls
perf_pmu_disable is called by core perf code before pmu->del and the enable function is called by core perf code afterwards. No need to call again within sparc_pmu_del. Ditto for pmu->add and sparc_pmu_add. Signed-off-by: David Ahern <david.ahern@oracle.com> Acked-by: Bob Picco <bob.picco@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
