Log:
Don't change the state of the system in acpi_tz_establish(). Before, we
would turn off all fans when initializing a zone. However, the HP Omnibook
500 generates a notify saying the zone needs to be re-evaluated whenever
its fan is switched on or off. This produced an infinite loop. Also, note
that running _SCP can generate the same notify.
Since we need to make sure old fan references are turned off when getting
new ones, run acpi_tz_monitor() first. This will turn off any unneeded
fans. Then, check for new settings. After that, run acpi_tz_monitor()
again to turn on/off any fans referenced by the new settings.
