Fix kernel NULL pointer dereference in xen-blkfront
When booting Xen Dom0 on a pre-release 3.2.1 hypervisor the system Oopses on a
"Unable to handle kernel NULL pointer dereference" in xenwatch.
From the backtrace it looks like backend_changed is calling bdget_disk
with a NULL pointer. Checking for NULL and returning ENODEV instead
allows the kernel to boot.
