Commit 39cef12a9 altered/fixed the inputvol processing to create
a multistep process when using an inputvol to create an encrypted
output volume; however, it unnecessarily assumed/restricted the
inputvol to be of 'raw' format only.
Modify the processing code to allow the inputvol format to be checked
and used in order to create the encrypted volume.
