A recent change for 'case LINUX_REBOOT_CMD_POWER_OFF' causes an endless
hang after 'halt -p' on my Macs with USB keyboard.
It went into rc1, but the hang in an usb device (1-1.3) shows up only
with rc3. Why is device_suspend() called anyway if the
system will go down anyway in a few milliseconds?
power down works again with this patch.
