perf test: Fix sample-parsing failure on non-x86 platforms

Executing 'perf test 27' fails on s390:

  [root@t35lp46 perf]# ./perf test -Fv 27
  27: Sample parsing
  --- start ---
  ---- end ----
  Sample parsing: FAILED!
  [root@t35lp46 perf]#

The commit fbefe9c2 ("perf tools: Support arch specific
PERF_SAMPLE_WEIGHT_STRUCT processing") changes the ins_lat to a
model-specific variable only for X86, but perf test still verify the
variable in the generic test.

Remove the ins_lat check in the generic test. The following patch will
add it in the X86 specific test.
