Update CDC Ethernet/RNDIS gadget driver to the latest:

    -	Basics of OTG support: providing the OTG descriptor
	in each configuration (as needed).   No HNP yet.

    -	Stop issuing partial-packet reads.  There's some hardware that
	only counts reads in packets, not bytes, so let's not bother.
	There are still software checks to catch framing gone wild.

    -	Fix a small bug that crept in with a memory leak fix: after
        RNDIS requests, ep0 responses would use the RNDIS completion
	handler even for non-RNDIS requests.
