Re: [libvirt] [PATCH 2/3] storage: Allow for inputvol to have any format for encryption

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.
