usb: Annotate access to USB buffers

Browse Source 
Annotate the USB transfer creation functions with the correct buffer
access attribute. Note that we only annotate them as read_only as the
functions may be used for sending and receiving.

Hopefully this will catch buffer overflows in drivers in the future.
