Subject: [PATCH] xenbus: drop useless LIST_HEAD in xenbus_write_watch() and
 xenbus_file_write()

Drop LIST_HEAD where the variable it declares is never used.

The declarations were introduced with the file, but the declared
variables were not used.

Fixes: 1107ba885e469 ("xen: add xenfs to allow usermode <-> Xen interaction")
