Roger Pau Monné f79cdf2998 xen: fix xenstore dev
Xenstore user-space device has two problems currently:
 - It does not correctly handle concurrent clients, because it's storing
   each client data in dev->si_drv1.
 - It does not correctly free this data when the client closes the device.

In order to solve both of this issues store the per-client data using
cdevpriv, which also comes with a hook in order to perform the necessary
cleanup on device close.

While there also make the device eternal.
