[sheepdog] [PATCH v4 0/2] fix 'qemu-img snapshot -a' operation for sheepdog

[Liu Yuan]

v4:
 - fix savevm, pass current vdi_id instead of parent_vdi_id

v3:
 - fix sheepdog's loadvm handling, don't rely on the write to create branch

v2:
 - add the comment to make things more clear
 - call sd_create_branch() after s->is_snapshot = true because after calling
   sd_create_branch, it is not snapshot anymore.

Nothing big, just two simple patches to enable this commind for sheepdog.
