[PATCH 4/4] b2c2: Always turn off receive stream

[Jemma Denson <jdenson@gmail.com>]

When letting an external device control the receive stream, it won't
know when there's demand for any feeds, so won't be turning off our
receive stream. This patch bring back control of turning it off in
this sitation.

The demod can still delay turning it on until it has data to send,
and still turn it off temporarily whilst it knows there's no
stream, such as whilst tuning.
