Description of problem:
After requiring qemu-img 2.10, we don't have to check if
prepare/teardown volumes is required. The logic of checking whether
prepare/teardown is required added in commit 7222af88 (create-snapshot:
Use unsafe option when creating snapshots), when at that time we still
used qemu-img<2.10 that didn't support unsafe operations
