dlt-load-control bugs

[alexmohr]

We found some issues internally and I'll provide fixes as soon as they are tested.
I'm opening this issue to communicate them, so other potential issues can be added here.

1. trace load limits is creating a large cpu load when a lot of context ids are filtered.
2. trace load limits lookup is not correct

DltTraceLoadSettings*
dlt_find_runtime_trace_load_settings(DltTraceLoadSettings *settings, uint32_t settings_count, const char* apid, const char* ctid) {
    if ((apid == NULL) || (strlen(apid) == 0))
        return NULL;

    DltTraceLoadSettings* app_level = NULL;
    size_t ctid_len = (ctid != NULL) ? strlen(ctid) : 0;

    for (uint32_t i = 0; i < settings_count; ++i) {
        if (strncmp(apid, settings->apid, DLT_ID_SIZE) != 0) {

the last line in the snippet should be

        if (strncmp(apid, settings[i].apid, DLT_ID_SIZE) != 0) {

instead of always comparing against the first element in the array.
