Ravi Bangoria 3a9e9a4709 perf trace: Fix call-graph output

Recently, Arnaldo fixed global vs event specific --max-stack usage with
commit bd3dda9ab0 ("perf trace: Allow overriding global --max-stack
per event"). This commit is having a regression when we don't use
--max-stack at all with perf trace. Ex,

  $ ./perf trace record -g ls
  $ ./perf trace -i perf.data
     0.076 ( 0.002 ms): ls/9109 brk(
     0.196 ( 0.008 ms): ls/9109 access(filename: 0x9f998b70, mode: R
     0.209 ( 0.031 ms): ls/9109 open(filename: 0x9f998978, flags: CLOEXEC

This is missing call-traces.
After patch:

  $ ./perf trace -i perf.data
     0.076 ( 0.002 ms): ls/9109 brk(
                                do_syscall_trace_leave ([kernel.kallsyms])
                                [0] ([unknown])
                                syscall_exit_work ([kernel.kallsyms])
                                brk (/usr/lib64/ld-2.17.so)
                                _dl_sysdep_start (/usr/lib64/ld-2.17.so)
                                _dl_start_final (/usr/lib64/ld-2.17.so)
                                _dl_start (/usr/lib64/ld-2.17.so)
                                _start (/usr/lib64/ld-2.17.so)
     0.196 ( 0.008 ms): ls/9109 access(filename: 0x9f998b70, mode: R
                                do_syscall_trace_leave ([kernel.kallsyms])
                                [0] ([unknown])
