[PATCH] perf report: Fix broken arrow at row 0 in annotate view

[Jin Yao]

When the jump instruction is displayed at the row 0 in annotate view,
the arrow is broken. An example:

 16.86 â   âââje     82
  0.01 â      movsd  (%rsp),%xmm0
       â      movsd  0x8(%rsp),%xmm4
       â      movsd  0x8(%rsp),%xmm1
       â      movsd  (%rsp),%xmm3
       â      divsd  %xmm4,%xmm0
       â      divsd  %xmm3,%xmm1
       â      movsd  (%rsp),%xmm2
       â      addsd  %xmm1,%xmm0
       â      addsd  %xmm2,%xmm0
       â      movsd  %xmm0,(%rsp)
       â82:   sub    $0x1,%ebx
 83.03 â    â jne    38
       â      add    $0x10,%rsp
       â      xor    %eax,%eax
       â      pop    %rbx
       â    â retq

The patch increments the row number before checking with 0.
