[PATCH i-g-t 09/21] tests/intel/xe_eudebug: Mold ufence reconnect test to disconnect

[Mika Kuoppala <mika.kuoppala@linux.intel.com>]

If debugger disconnects, the driver will automatically ack all
ufences as we have 1:1 mapping between debuggers and drm clients.

In old way of connecting, reconnecting test made sense but it
does not anymore.

Convert the test to just disconnect the debugger.
