In drivers/usb/core/hcd-pci.c, the code forgets to set hcd->state to
USB_STATE_SUSPENDED on suspend.  The effect is that on resume, the
code refuses to wake the HCD up, and instead prints a message saying
the interface hasn't been suspended.

The patch below fixes this.  It is against 2.6.0-test6.  With this
patch I can suspend and resume my Apple PowerBook G4, and the USB
works after resuming.
