scripts/gdb: slab: update field names of struct kmem_cache 

The commit 5ba6bc27b1 ("slab: decouple pointer to barn from
kmem_cache_node") reorganized the struct kmem_cache to factor out the
per-node fields to the new struct kmem_cache_per_node_ptrs.  This causes
the gdb scripts for lx-slabinfo and lx-slabtrace fail as they still
reference the old structure.

Adjust the gdb scripts to match the current state of struct kmem_cache.
