habanalabs: add validation cs counter, fix misplaced counters

2020-12-28T06:47:39Z

Up until now validation errors were counted in the parsing field of the cs_counters struct, so we added a new counter and increased it when needed. In addition, there were some locations where only one of the counters was updated (ctx or aggregate) so add the second one to be updated as well.
