Mauro Carvalho Chehab c4018fa2e4 [media] dib0700: fix RC support on Hauppauge Nova-TD 
The RC support o Nova-TD is broken, as the RC endpoint there
is an interrupt endpoint.

That produces an ugly calltrace at the Kernel logs:

	WARNING: CPU: 2 PID: 56 at drivers/usb/core/urb.c:450 usb_submit_urb+0x1fd/0x5c0()
	usb 1-1.2: BOGUS urb xfer, pipe 3 != type 1

Fix it by detecting if the endpoint is bulk or interrupt.

Tested with both Hauppauge Nova-TD model 52009 (interrupt) and with a
		 Prolink Pixelview SBTVD model PV-D231U (bulk).
