Remove virt.pool_delete fast parameter (saltstack#178)

There are two reasons to remove this parameter without deprecating it:
 * the meaning has been mistakenly inversed
 * fast=True will raise an exception for every libvirt storage backend
since that flag has never been implemented in any of those.

Fixes issue saltstack#54474
