This extra flag is causing the FS pool to diverge from semantics of the
other pool types. As per the comment inthe header, the 'VIR_STORAGE_POOL_BUILD_NEW'
is defined to be a full initialize of the pool from scratch. For logical pool
this pvcreate + vgcreates the data. For disk backend this writes a new empty
partition table label. For FS pools, this should be formatting the filesystem.
The type of filesystem is actually visible via the XML, so we don't need to
worry about ext3/4/etc in this context.
