x86/hpet: replace disabling of legacy broadcast
... by the call to hpet_disable() added in the immediately preceding
patch.
In order to retain the behavior intended by c/s 23776:0ddb4481f883,
implement one of the alternative options pointed out there: remove CPUs
from the online map in __stop_this_cpu() (and hence doing so in
stop_this_cpu() is no longer needed).
