Log Message:
usb: Omit bogus assertions about struct usbd_pipe::up_intrxfer.
These assertions were only valid for pipes at UE_IN_DIR, UE_INTERRUPT
endpoints created with usbd_open_pipe_intr, which uses up_intrxfer to
pass the struct usbd_xfer object to usbd_close_pipe to free later.
In contrast, for pipes at UE_OUT_DIR, UE_INTERRUPT endpoints,
up_intrxfer is never initialized, so the assertion cannot be right.
In principle we might even have more than one outstanding interrupt
transfer at a time, rendering the point of the assertion moot anyway.
Found by interrupting a uhidev write to a u2f device.
