[PATCH] perf Documentation: Correct branch stack sampling call-stack option

[Dapeng Mi]

The correct call-stack option for branch stack sampling should be "stack"
instead of "call_stack". Correct it.

$perf record -e instructions -j call_stack -- sleep 1
unknown branch filter call_stack, check man page

 Usage: perf record [<options>] [<command>]
    or: perf record [<options>] -- <command> [<options>]

    -j, --branch-filter <branch filter mask>
                          branch stack filter modes
