[sheepdog] [PATCH stable-0.9 2/4] dog: fix segfault bug of getting snapshot for "LOCK_STATE_SHARED" VDI.

[Hitoshi Mitake]

From: Teruaki Ishizaki <ishizaki.teruaki at lab.ntt.co.jp>

After iSCSI initiator logins to the iSCSI target of the VDI,
getting snapshot for that volume causes segault.
This patch fixes false loop.
