clarified proposal for the preemption note

The handbook states in a note on CARP:
> If preemption has been enabled, hostc.example.org might not release the v=
irtual IP
> address back to the original master server.

The preemption setting does the opposite of what I would interpret this
sentence to convey. Preemption needs to be enabled in order for the system =
with
a lower advskew value (the original master) to take the address back.

In writing this, I wonder if it also needs a sentence on where to enable
preemption (master, backup or both...). I'd assume there are very few
scenarios, where different settings on nodes in the same group would be use=
ful
or necessary.

I have attached a proposed change for this note.
