Subject[ 68/73] [media] hdpvr: fix race conditon during start of streaming
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Janne Grunau <j@jannau.net>

commit afa159538af61f1a65d48927f4e949fe514fb4fc upstream.

status has to be set to STREAMING before the streaming worker is
queued. hdpvr_transmit_buffers() will exit immediately otherwise.
