Wander Lairson Costa dfd04add59 kmem/tracing: add kmem name to kmem_cache_alloc tracepoint ...

The kmem_cache_free tracepoint includes a "name" field, which allows for
easy identification and filtering of specific kmem's.  However, the
kmem_cache_alloc tracepoint lacks this field, making it difficult to pair
corresponding alloc and free events for analysis.

Add the "name" field to kmem_cache_alloc to enable consistent tracking and
correlation of kmem alloc and free events.
