net: sched: cls_u32: use hash_ptr() for tc_u_hash 

After the change to the tp hash, we now get a build warning
on 32-bit architectures:

net/sched/cls_u32.c: In function 'tc_u_hash':
net/sched/cls_u32.c:338:17: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
  return hash_64((u64) tp->chain->block, U32_HASH_SHIFT);

Using hash_ptr() instead of hash_64() lets us drop the cast
and fixes the warning while still resulting in the same hash
value.
