    graid: Set G_CF_DIRECT_SEND for task consumer.
    
    Unlike normal consumers all taste consumer I/O is synchronous, done
    with g_read_data() and without any locks held.  It makes no sense to
    delegate I/O submission to g_down thread.
    
    This should remove number of context switches during disk retaste.
    
    MFC after:      2 weeks
    
    (cherry picked from commit 0d8cec7658d50e4190899376330c2c1eb5d8c659)
