[PATCH] usbcore: small changes to HCD glue layer

This patch (as549) introduces two small changes in the HCD glue layer.
The first simply removes a redundant test.  The second allows root-hub
polling to continue for a single iteration after a host controller dies;
this is needed for the patch that follows.
