We're about to disallow creation of a qcow2 encrypted storage
volume, so let's remove the qcow encryption element from the
tests which are testing whether other format='qcow2' related
features work properly.

This patch adds support to qcow2 formatted filesystem object storage by
instructing qemu-img to build them with preallocation=falloc whenever the
XML described storage <allocation> matches its <capacity>. For all other
cases the filesystem stored objects are built with preallocation=metadata.

In virStorageVolCreateXML, add VIR_VOL_XML_PARSE_NO_CAPACITY
to the call parsing the XML of the new volume to make the capacity
optional.
If the capacity is omitted, use the capacity of the old volume.
We already do that for values that are less than the original
volume capacity.
