    ixv: Remove unused loader tunables
    
    The flow_control and hdr_split variables have never been read.  VF
    flow control is controlled by the PF, while implementing header split
    would require receive-path support that ixv does not provide.
    
    (cherry picked from commit 8eeb25899afd7818d99ce1500be27ae8d992131f)
