ACPI: suspend: don't let device _PS3 failure prevent suspend
6328a57401dc5f5cf9931738eb7268fcd8058c49
"Enable PNPACPI _PSx Support, v3"
added a call to acpi_bus_set_power(handle, ACPI_STATE_D3)
to pnpacpi_disable_resource() before the existing call
to evaluate _DIS on the device.
This caused suspend to fail on the system in
http://bugzilla.kernel.org/show_bug.cgi?id=13243
because the sanity check to verify we entered _PS3
failed on the serial port.
As a work-around, that sanity check can be disabled
system-wide with "acpi.power_nocheck=1"
Or perhaps we should just shrug off the _PS3 failure
and carry on with _DIS like we used to -- which is
what this patch does.
