Subject: [PATCH] Bluetooth: Only schedule raw queue when user channel is
active
When the user channel is set and an user application has full control
over the device, do not bother trying to schedule any queues except
the raw queue.
This is an optimization since with user channel, only the raw queue
is in use.
