Currently 'perf c2c report' determines display mode using the --stdio
option, but it could be a problem if stdout is not a tty since
setup_browser falls back to stdio in this case.
But perf c2c didn't know this and tried to use TUI browser anyway. It
should check "use_browser" variable instead.
For example, the following command showed nothing and broke terminal
setting. Now it's fixed..
$ perf c2c report | head

Committer notes:
When trying it without a proper perf.data file it results in a stuck
terminal, just as Namhyung reported above:
[acme@jouet ~]$ perf c2c report | head
WARNING: no sample cpu value[acme@jouet ~]$
One has to kill it from some other xterm. Confirm that this patch fixes
it:
After:
$ perf c2c report | head
