Sean Young 0c84bde4f3 media: Revert "media: dvb-usb: Fix unexpected infinite loop in dvb_usb_read_remote_control()"
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.
