[PATCH 11/11] s390/mm: Remove the now unused mem_encrypt_active() function

The mem_encrypt_active() function has been replaced by prot_guest_has(),
so remove the implementation. Since the default implementation of the
prot_guest_has() matches the s390 implementation of mem_encrypt_active(),
prot_guest_has() does not need to be implemented in s390 (the config
option ARCH_HAS_PROTECTED_GUEST is not set).
