Subject: [PATCH] snapshot: fix regression with system checkpoints

Regression introduced in commit d6f6b2d194c.  Running
'virsh snapshot-create dom' would mistakenly report that
disks can only be specified for disk snapshots.

* src/conf/domain_conf.c (virDomainSnapshotDefParseString): Only
give error about no disk support when <disk> was found.
