ref: #188

Signed-off-by: Pawan pawan@mayadata.io

Why is this PR required? What issue does it fix?:

ZFS does not create the zvol if volume size is not multiple of
the volblocksize. There are use cases where customer will create
a PVC with size as 5G, which will be 5 * 1000 * 1000 * 1000 bytes
and this is not the multiple of default volblocksize 8k.

What this PR does?:
In ZFS, volblocksize and recordsize must be power of 2 from 512B to 1M,
so keeping the size in the form of Gi or Mi should be
sufficient to make volsize multiple of volblocksize/recordsize.
