platform/x86: ISST: Reset core count to 0

Browse Source 
Based on feature revision, number of buckets can be less than the
TRL_MAX_BUCKETS. In that case core counts in the remaining buckets
can be set to some invalid values.

Hence reset core count to 0 for all buckets before assigning correct
values.
