[PATCH v3] perf tools: Add missing case value

From: Solomon Tan
Date: Tue Mar 19 2019 - 23:20:49 EST


The following error was thrown when compiling `tools/perf` using OpenCSD
v0.11.1. This patch fixes said error.

```
CC util/intel-pt-decoder/intel-pt-log.o
CC util/cs-etm-decoder/cs-etm-decoder.o
util/cs-etm-decoder/cs-etm-decoder.c: In function
âcs_etm_decoder__buffer_rangeâ:
util/cs-etm-decoder/cs-etm-decoder.c:370:2: error: enumeration value âOCSD_INSTR_WFI_WFEâ not handled in switch [-Werror=switch-enum]
switch (elem->last_i_type) {
^~~~~~
CC util/intel-pt-decoder/intel-pt-decoder.o
cc1: all warnings being treated as errors
```

Because `OCSD_INSTR_WFI_WFE` case was only added after v0.11.0, the minimum
required OpenCSD library version for this patch is no longer v0.10.0.
