[PATCH v2 5/9] perf anntoate browser: Fix the toggle total period view to show period, not number of samples

[Taeung Song]

Currently the toggle total period view on the annotate TUI
shows the number of samples, not period like below.
So fix the toggle total period view on the annotate TUI like below.

  $ perf annotate --show-total-period

Before:

       │    Disassembly of section .text:
       │
       │    0000000000109a90 <_mcount@@GLIBC_2.2.5>:
       │      sub    $0x38,%rsp
     3 │      mov    %rax,(%rsp)
     3 │      mov    %rcx,0x8(%rsp)

After:

           │    Disassembly of section .text:
           │
           │    0000000000109a90 <_mcount@@GLIBC_2.2.5>:
           │      sub    $0x38,%rsp
   2204022 │      mov    %rax,(%rsp)
   2207405 │      mov    %rcx,0x8(%rsp)
