[Qemu-devel] [PATCH 16/21] VMDK: move 'static' cid_update flag to bs field |

From: Fam Zheng <address@hidden>
Cid_update is the flag for updating CID on first write after opening the
image. This should be per image open rather than per program life cycle,
so change it from static var of vmdk_write to a field in BDRVVmdkState.
