Victor Toso b4c32cbf06 qapi: fix example of query-hotpluggable-cpus command

Problem was noticed when using the example as a test case for Go
bindings.

# @LostTickPolicy:
#
# Policy for handling lost ticks in timer devices. Ticks end up getting

#
# @discard: throw away the missed ticks and continue with future injection
# normally. The guest OS will see the timer jump ahead by a
# potentially quite significant amount all at once, as if the
# intervening chunk of time had simply not existed; needless to
# say, such a sudden jump can easily confuse a guest OS which is
# not specifically prepared to deal with it. Assuming the guest
# OS can deal correctly with the time jump, the time in the guest
# and in the host should now match.
#
# @delay: continue to deliver ticks at the normal rate. The guest OS will
# not notice anything is amiss, as from its point of view time will
# have continued to flow normally. The time in the guest should now
# be behind the time in the host by exactly the amount of time during
# which ticks have been missed.
#
# @slew: deliver ticks at a higher rate to catch up with the missed ticks.
# The guest OS will not notice anything is amiss, as from its point
# of view time will have continued to flow normally. Once the timer
# has managed to catch up with all the missing ticks, the time in
# the guest and in the host should match.
