Mate Lakat b1dc9bd5e4 xenapi: enable block device access for stack user
Although nova is setting the permissions on block devices, sometimes it
fails, and that results in an instance failing to launch. It is only an
issue for 3-part images, and images accessed through block devices. This
patch adds an udev rule, so that devices will be accessible.

fixes bug 1218251
