USB: Make device reset stop retrying after disconnect
This patch (as898) changes the port reset code in the hub driver. If
a connect change occurs, it is reported the same way as a disconnect
(which of course is what it really is).
It also changes usb_reset_device(), to prevent the routine from futilely
retrying the reset after a disconnect has occurred.
