KVM: s390: Don't use %pK through debug printing

[ Upstream commit 0c7fbae5 ]

Restricted pointers ("%pK") are only meant to be used when directly
printing to a file from task context.
Otherwise it can unintentionally expose security sensitive,
raw pointer values.

Use regular pointer formatting instead.
