Subject: [PATCH 28/41] perf report: Set proper sort__mode for the branch option

From: "naota@...sp.net" <naota@...sp.net>

When you specify "--branch-stack"("-b" for short) or
"--no-branch-stack", "branch_mode" variable is set to 1 or 0
respectively. However, the code is just checking if the variable is -1
or not, ignoring "branch_mode == 1" case. Thus "perf report -b" dose not
show its result with the branch sorted mode. This patch fix the problem.
