reset_counter marks the reset counter number once the context is created, shouldn't be changed due to query.
To keep U/K interface on the ctx_query and keep ctx's reset_counter logic compatible with GPU RESET feature, now use another var named "reset_counter_query" to replace the original checked & updated in amdgpu_ctx_query.
