Subject: [PATCH v4 3/9] perf anntoate browser: Fix the toggle total period view showing number of samples

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)
