Fix parser checking of storage pool device

Browse Source 
The storage backend implementations all presume that the XML parser
is validating correctness of the source specification. The check for
a source device was lost at some point. This allowed for a potential
crash in the disk backend. Re-introduce the sanity check

* src/conf/storage_conf.c: Re-add check for source device
