freezer: fix sleep of death with binder

When going from idle->suspend (without usb plugged in)
our pvr driver crashes because of a bad freezer call.
After pvr all process died and the phone reboots with a
hot reboot.

This was caused by binder using the new freezer code.
This fixes the sleep of death and also keeps functionality
for binder.
