USB: autosuspend code consolidation

Browse source

This patch (as813) gathers together common code for USB interface
autosuspend/autoresume. 

It also adds some simple checking at the time an autosuspend request
is made, to see whether the request will fail.  This way we don't
add a workqueue entry when it would end up doing nothing.
