[PATCH] USB: Use num_altsetting in usbnet and usbtest

This patch fixes usbnet and usbtest.  When checking endpoints, they
iterate through all interfaces out to intf->max_altsetting, but they
should only go up to intf->num_altsetting.  The max_altsetting value
refers to the amount of space _allocated_ for usb_host_interface
structures, not the number that are really in use.
