dsp: platform: Prevent overflow of arithmetic on event_data_length

Resolves the following warning from GCC's static analyzer:

```
../src/dsp/platform.c: In function ‘encode_platform_event_message_req’:
../src/dsp/platform.c:1246:9: error: use of attacker-controlled value ‘event_data_length’ as size without upper-bounds checking [CWE-129] [-Werror=analyzer-tainted-size]
 1246 |         memcpy(request->event_data, event_data, event_data_length);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
