[libvirt] [PATCHv2 11/13] snapshot: simplify indentation of disk encryption xml

[Eric Blake]

Use auto-indent in more places.

* src/conf/storage_encryption_conf.h (virStorageEncryptionFormat):
Drop parameter.
* src/conf/storage_encryption_conf.c (virStorageEncryptionFormat)
(virStorageEncryptionSecretFormat): Simplify with auto-indent.
* src/conf/domain_conf.c (virDomainDiskDefFormat): Adjust caller.
* src/conf/storage_conf.c (virStorageVolTargetDefFormat): Likewise.
