Mike Rapoport 9a436f8ff6 PM: hibernate: disable when there are active secretmem users 
It is unsafe to allow saving of secretmem areas to the hibernation
snapshot as they would be visible after the resume and this essentially
will defeat the purpose of secret memory mappings.

Prevent hibernation whenever there are active secret memory users.
