percpu_ref->pcpu_count is a percpu pointer with a status flag in its lowest bit. As such, it always goes through arithmetic operations which is very cumbersome to do on a pointer. It has to be first casted to unsigned long and then back. Let's just make the field unsigned long so that we can skip the first casts. While at it, rename it to pcpu_counter_ptr to clarify that it's a pointer value.
