German Gomez 05b5a9d628 perf tools: Apply correct label to user/kernel symbols in branch mode
In branch mode, the branch symbols were being displayed with incorrect
cpumode labels. So fix this.

For example, before:
  # perf record -b -a -- sleep 1
  # perf report -b

  Overhead  Command  Source Shared Object  Source Symbol               Target Symbol
     0.08%  swapper  [kernel.kallsyms]     [k] rcu_idle_enter          [k] cpuidle_enter_state
 ==> 0.08%  cmd0     [kernel.kallsyms]     [.] psi_group_change        [.] psi_group_change
     0.08%  cmd1     [kernel.kallsyms]     [k] psi_group_change        [k] psi_group_change

After:
  # perf report -b

  Overhead  Command  Source Shared Object  Source Symbol               Target Symbol
     0.08%  swapper  [kernel.kallsyms]     [k] rcu_idle_enter          [k] cpuidle_enter_state
     0.08%  cmd0     [kernel.kallsyms]     [k] psi_group_change        [k] pei_group_change
     0.08%  cmd1     [kernel.kallsyms]     [k] psi_group_change        [k] psi_group_change

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
