s390/cmf: fix virtual vs physical address confusion

Browse Source 
The measurement block origin address is an absolute address; therefore
add a missing virt_to_phys() translation to the cmf_activate() inline
assembly.

This doesn't fix a bug, since virtual and physical addresses are
currently identical.
