core: DiskImageDynamicDao - deadlock caused by wrong sorting

updateAllDiskImageDynamicWithDiskIdByVmId is supposed to sort
the DiskImageDynamicDao objects its updating in order to avoid
deadlocks. Currently the sorting is done on the first object
of the pair which is the vm id instead of the the image group id.

This patch changes the sorting to be according the image group id as
it was supposed to be.
