cleanup USB endpoint direction display

There are two fileds reported from the kernel by
linux/drivers/usb/mon/mon_bin.c: the xfer_type and the epnum. The xfer_type is
at offset 9 and the epnum is at offset 10. The xfer_type only contains the four
possible transfer types: PIPE_CONTROL, PIPE_ISOCHRONOUS, PIPE_BULK and
PIPE_INTERRUPT (see xfer_to_pipe[] in mon_bin.c). The epnum field contains the
direction at the most significant bit and the lower 7 bits contain the endpoint
value itself.
