xenbus: allow any xenbus command over /proc/xen/xenbus
When xenstored is in another domain, we need to be able to send any
command over xenbus. This doesn't pose a security problem because
its up to xenstored to determine whether a given client is allowed
to use a particular command anyway.
From linux-2.5.18-xen.hg 68d582b0ad05.
