USB: core: Disable remote wakeup for freeze/quiesce
The PM_EVENT_FREEZE and PM_EVENT_QUIESCE messages should cause the
device to stop generating interrupts. USB core was previously allowing
devices that were already runtime suspended to keep remote wakeup
enabled if they had gone down that way. This violates the contract with
pm, and can potentially cause MSI interrupts to be lost.
Change that so that if a device is runtime suspended with remote wakeups
enabled, it will be resumed to ensure remote wakeup is always disabled
across a freeze.
