[PATCH] cgroup: Use %p for pointer formatting

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

Since commit ad67b74d2469d ("printk: hash addresses printed with
%p") pointers are hashed by default and the behaviour can be controller
by `hash_pointers' boot argument.
Removing %pK makes it possible to remove its handling from the library.
The policy on %p is to not introduce new ones.

Since this looks vital to the debugging of cgroups, keep the pointer
output.

Use %p instead %pK.
