acpi_pm: Clear pmtmr_ioport if acpi_pm initialization fails
If the acpi pm timer throws invalid data, clear pmtmr_ioport
so the pm timer won't accidentally be used.
This was found when using Xen where there is a acpi pm reported,
but gives bogus values, and other code was continuing to try
to use the pm timer after the initialization failed.
[jstultz: Catch additional failure and reword changelog message. ]
