cx18: Add missing lock for when the irq handler manipulates the queues
From: Andy Walls <awalls@radix.net>
cx18: Add missing lock for when the irq handler manipulates the queues. This
was a potential source of stream queue corruption. Also changed the name of
cx18_queue_find_buf() to cx18_queue_get_buf_irq().
Priority: high
