ffaaaa0a34 casadm: don't cast a float to an int explicitly 
If an underflowed float number was casted to an int explicitly, it's value was
rounded to a lower value.

Using `round()` function ensures that the number will be always rounded to a
nearest integer.

68b68db9c0 Zero metadata if on-disk version differs from current 
Kernel adapter now returns is_cache_device=1 and newly added
metadata_compatible=0 in case of metadata detected with
differing version (instead of is_cache_device = 0).

This allows zero-superblock command to recognize old
cache instance and clear it.

casadm --script --check-cache-device still returns 'Is cache'='no'
in this case, as this layer only cares about metadata in current
version to be able to detect dirty datas tatus.
