Xen: Fix snapshots when use_cow=True.
This fixes an issue where use_cow=True would sporadically cause snapshot
corruption.
The root cause was a race-condition where the VM's sm_config was
sometimes out-of-sync with the underlying VHDs.
The solution is to force an SR rescan immediately after taking a
snapshot so that any VHD parent-pointer modifications are propogated
into the sm_config so that _walk_vdi_chain will receive accurate
information.
