07089083a5 drm/xe/tracing: Fix a potential TP_printk UAF 
The commit
afd2627f72 ("tracing: Check "%s" dereference via the field and not the TP_printk format")
exposes potential UAFs in the xe_bo_move trace event.

Fix those by avoiding dereferencing the
xe_mem_type_to_name[] array at TP_printk time.

Since some code refactoring has taken place, explicit backporting may
be needed for kernels older than 6.10.

In multi-gpu environments it is important to know the device
bo/vm belongs to. The tracing information includes the device_id
to indicate the device the event is associated with.

v2: Use variable sized variant to display dev name(Gustavo)
v3: Pass single argument to __assign_str to fix kunit error
v4: Minor cleanups(Gustavo)
