commit 0c84bde4f3 upstream.
This reverts commit 2052138b7d.
This breaks the TeVii s480 dual DVB-S2 S660. The device has a bulk in
endpoint but no corresponding out endpoint, so the device does not pass
the "has both receive and send bulk endpoint" test.
Seemingly this device does not use dvb_usb_generic_rw() so I have tried
removing the generic_bulk_ctrl_endpoint entry, but this resulted in
different problems.
As we have no explanation yet, revert.
