[PATCH] qemuProcessSetupDisksTransientSnapshot: Skip enabling transientOverlayCreated flag

From: Masayoshi Mizuma <m.mizuma(a)jp.fujitsu.com&gt; QEMU_DOMAIN_DISK_PRIVATE(disk)->transientOverlayCreated flag gets true unexpectedly on qemuProcessSetupDisksTransientSnapshot() when the disk has <transient shareBacking='yes'> option. The flag should be enabled on qemuDomainAttachDiskGeneric() after the overlay setup is completed. Skip enabling transientOverlayCreated for the disk here.
