perf test: Add missing verbose output explaining the reason for failure

Browse source 
One of the branches leading to an error had no debug message emitted,
fix it, the new lines are:

  # perf test -v kallsyms
<SNIP>
  0xffffffff81001000: diff name v: xen_hypercall_set_trap_table k: hypercall_page
  0xffffffff810691f0: diff name v: try_to_free_pud_page k: try_to_free_pmd_page
<SNIP>
  0xffffffff8150bb20: diff name v: wakeup_expire_count_show.part.5 k: wakeup_active_count_show.part.7
  0xffffffff816bc7f0: diff name v: phys_switch_id_show.part.11 k: phys_port_name_show.part.12
  0xffffffff817bbb90: diff name v: __do_softirq k: __softirqentry_text_start
<SNIP>

This in turn exercises another bug, still under investigation, because those
aliases _are_ in kallsyms, with the same name...
