bug 6904: during volume creation, we were NOT converting the size of the parent disk offering (which is in MB), to bytes. This is the size used to create the volume. I am adding the appropriate multipliers. Other flows like creating volume from snapshot etc should remain unaffected, as the parent volume created from the disk offering will be set right.

status 6904: resolved fixed
