gpu: nvgpu: replace %p with %px for cache name

Browse Source 
%p prints (ptrval) instead of hexadecimal value until it gathers
enough entropy. During early boot stage, it can make invalid
cache name like "nvgpu-cache-0x        (ptrval)-128-1" and that
kind of cache name can make failure of kmem_cache_create().
To avoid invalid cache name, replace %p with %px for cache name.
