Ian Rogers 5b10c18d1b perf parse-events: Avoid SEGV if PMU lookup fails for legacy cache terms 
libfuzzer found the following command could SEGV:

  $ perf stat -e cpu/L2,L2/ true

This is because the L2 term rewrites the perf_event_attr type to
PERF_TYPE_HW_CACHE which then fails the PMU lookup for the second
legacy cache term.

The new failure is consistent with repeated hardware terms:

  $ perf stat -e cpu/L2,L2/ true
  event syntax error: 'cpu/L2,L2/'
                              \___ Failed to find PMU for type 3

  Initial error:
  event syntax error: 'cpu/L2,L2/'
                              \___ Failed to find PMU for type 3
  Run 'perf list' for a list of valid events

   Usage: perf stat [<options>] [<command>]

      -e, --event <event>   event selector. use 'perf list' to list available events
  $ perf stat -e cpu/cycles,cycles/ true
  event syntax error: 'cpu/cycles,cycles/'
                                  \___ Failed to find PMU for type 0

  Initial error:
  event syntax error: 'cpu/cycles,cycles/'
                                  \___ Failed to find PMU for type 0
  Run 'perf list' for a list of valid events

   Usage: perf stat [<options>] [<command>]

      -e, --event <event>   event selector. use 'perf list' to list available events

Committer testing:

Before:

  $ perf stat -e cpu/L2,L2/ true
  Segmentation fault (core dumped)
  $

After:

  $ perf stat -e cpu/L2,L2/ true
  event syntax error: 'cpu/L2,L2/'
                              \___ Failed to find PMU for type 3
