    ipfilter: Fix struct ifnet pointer type
    
    The fr_info struct contains a summary of a packet. One of its fields
    is a pointer to the ifnet struct the packet arrived on. It is pointed
    to by a void* because ipfilter supports multiple O/Ses. Unfortunately
    this makes it difficult it examine with DTrace. Defining fin_ifp as a
    pointer to an ifnet struct makes the struct it points to using a DTrace
    script possible.
    
    (cherry picked from commit 8f19f3d31a7224c502c36dd16f1321b802e4da60)
