tracing: Add correct/incorrect to sort keys for branch annotation output

The branch annotation is a bit difficult to see the worst offenders
because it only sorts by percentage:

 correct incorrect  %        Function                  File              Line
 ------- ---------  -        --------                  ----              ----
       0      163 100 qdisc_restart                  sch_generic.c        179
       0      163 100 pfifo_fast_dequeue             sch_generic.c        447
       0        4 100 pskb_trim_rcsum                skbuff.h             1689
       0        4 100 llc_rcv                        llc_input.c          170
       0       18 100 psmouse_interrupt              psmouse-base.c       304
       0        3 100 atkbd_interrupt                atkbd.c              389
       0        5 100 usb_alloc_dev                  usb.c                437
       0       11 100 vsscanf                        vsprintf.c           1897
       0        2 100 IS_ERR                         err.h                34
       0       23 100 __rmqueue_fallback             page_alloc.c         865
       0        4 100 probe_wakeup_sched_switch      trace_sched_wakeup.c 142
       0        3 100 move_masked_irq                migration.c          11

Adding the incorrect and correct values as sort keys makes this file a
bit more informative:

 correct incorrect  %        Function                  File              Line
 ------- ---------  -        --------                  ----              ----
       0   366541 100 audit_syscall_entry            auditsc.c            1637
       0   366538 100 audit_syscall_exit             auditsc.c            1685
       0   115839 100 sched_info_switch              sched_stats.h        269
       0    74567 100 sched_info_queued              sched_stats.h        222
       0    66578 100 sched_info_dequeued            sched_stats.h        177
       0    15113 100 trace_workqueue_insertion      workqueue.h          38
       0    15107 100 trace_workqueue_execution      workqueue.h          45

       0     2750 100 sched_move_task                sched.c              10110
       0     1815 100 pre_schedule_rt                sched_rt.c           1462
