    Rx: Do not drop call lock in rx_WriteProc* and rx_ReadProc*
    
    rx_WriteProc and rx_ReadProc has special fast logic that
    handles the most frequent case.  This code was called
    without obtaining the call lock. However, each of these functions
    must obtain the call lock for the queue_IsNotEmpty() test and
    must re-obtain the call lock if the rxi_XXX variant is required.
    Dropping the lock and re-obtaining it is more expensive than
    holding it across the memcpy.  Therefore, we shouldn't drop the
    lock until we are done.
