The driver reported an warning in usb_submit_urb() which is caused by
wrong endpoint type.

[    3.295630] usb 1-1: BOGUS urb xfer, pipe 3 != type 1
[    3.295916] WARNING: CPU: 0 PID: 33 at drivers/usb/core/urb.c:503 usb_submit_urb+0xcd9/0x18b0
[    3.298155] RIP: 0010:usb_submit_urb+0xcd9/0x18b0
[    3.302451] Call Trace:

[    3.302938]  bfusb_open+0x50/0x90 [bfusb]

Fix this by checking the endpoint type at first.
