Export hibernation_in_progress() to be used by other modules. Add its
signature when hibernation config isn't enabled as well.

I wonder if you actually want to have pm_sleep_transition_in_progress()
exported instead.  "Logically" I would expect cancelling a hibernate and
cancelling a suspend should work similarly.

Well, it does AFAICS, except that only the "freeze" and "poweroff"
transitions can be aborted during hibernation.  This is analogous to
aborting a suspend transition.

The missing part is a mechanism to cancel hibernation between image
creation and the "poweroff" transition.
