USB: check the endpoint type against the pipe type

This patch (as1316) adds some error checking to usb_submit_urb().
It's conditional on CONFIG_USB_DEBUG, so it won't affect normal users.
The new check makes sure that the actual type of the endpoint
described by urb->pipe agrees with the type encoded in the pipe value.

The USB error code documentation is updated to include the code
returned by the new check, and the usbfs SUBMITURB handler is updated
to use the correct pipe type when legacy user code tries to submit a
bulk transfer to an interrupt endpoint.
