app/vminsert/influx: replace hybrid channel-based pool+sync.Pool with plain sync.Pool for pushCtx

Browse source 
The memory usage for plain sync.Pool doesn't increase comparing to the memory usage for the hybrid scheme,
so it is better to use plain sync.Pool in order to simplify the code and make it more readable and maintainable.

This is a follow-up for c22da2f917
