storage: fix build with iscsi

The previous storage patch missed an instance affected by the struct
member rename.  It also had some botched whitespace detected by
'make check'.

* src/storage/storage_backend_iscsi.c
(virStorageBackendISCSIFindPoolSources): Adjust to new struct.
* src/conf/storage_conf.c (virStoragePoolSourceFormat): Fix
indentation.
