[BUG] perf mem: perf mem report fails in TUI mode

I was running a couple of tests with perf mem from tip.git and
found that perf mem -t load rep was failing only in TUI mode.
With --stdio, it works fine. I did a bit of investigation and found
out that the TUI mode is failing because some symbol (kernel)
is showing up with a huge (negative) size. I don't understand
the connection between the TUI vs. tty browser and symbols.

To reproduce:
$ perf mem -t load rec my_test_program
$ perf mem -t load rep
$ perf mem -t load rep --stdio

Debugging with TUI is a pain, so I stopped.

I have a patch to improve perf mem a bit but I'd like to get this problem
fixed first.

Maybe you have a idea of what's going on.
