USB: Don't resume root hub if the controller is suspended
Root hubs can't be resumed if their parent controller device is still
suspended. This patch (as925) adds a check for that condition in
hcd_bus_resume() and prevents it from being treated as a fatal
controller failure.
ehci-hcd is updated to add the corresponding test. Unnecessary
debugging messages are removed from uhci-hcd and dummy-hcd. The
error return code from dummy-hcd is changed to -ESHUTDOWN, the same as
the others. ohci-hcd doesn't need any changes.
Suspend handling in the non-PCI host drivers is somewhat hit-and-miss.
This patch shouldn't have any effect on them.
