This patch (as992) fixes a recently-added bug.  During a FREEZE or
PRETHAW suspend notification, non-root devices don't actually get
suspended.  So we shouldn't tell their parent hubs that they did.

(This code path used to be skipped over, until the FREEZE/PRETHAW test
got moved out of usb_suspend_both() into generic_suspend().)
