staging: bcm2835-camera: Do not bulk receive from service thread
vchi_bulk_queue_receive will queue up to a default of 4
bulk receives on a connection before blocking.
If called from the VCHI service_callback thread, then
that thread is unable to service the VCHI_CALLBACK_BULK_RECEIVED
events that would enable the queue call to succeed.
Add a workqueue to schedule the call vchi_bulk_queue_receive
in an alternate context to avoid the lock up.
