drm/xe/observation: Drop empty sysctl table entry

An empty sysctl table entry was inadvertently left behind for observation
sysctl. The breaks on 6.11 with the following errors:

[  219.654850] sysctl table check failed: dev/xe/(null) procname is null
[  219.654862] sysctl table check failed: dev/xe/(null) No proc_handler

Drop the empty entry.
