Just drop/lvremove the cache-pool and create the new one again.
There is no specific 'zeroing' metadata command.

And as said - newer tool will ZERO by default and you need to pass -Zn to 
avoid zeroing (in case you want to reattach same cache-pool to unused data - 
but as said you need to be skilled user knowing what you are doing for this 
use case)
