kvm: suspend a VM before snapshot deletion (see PR #3193) (#3194)
To make sure that a qemu2-image won't be corrupted by the snapshot deletion
procedure which is being performed after copying the snapshot to a secondary
store, I'd propose to put a VM in to suspended state.
Additional reference: https://bugzilla.redhat.com/show_bug.cgi?id=920020#c5
Fixes #3193
