qtdemux: Don't stop task when resetting

Browse source 
This is a regression that was introduced in
cca2f555d1 (yes, 9 years ago).

The only place where a demuxer streaming thread should be stopped is when the
sinkpad is deactivated from pull mode (i.e. PAUSED->READY).

Attempting to stop the task in this function would cause this to happen when a
FLUSH_STOP or STREAM_START event is received... which can cause deadlocks.
