    iflib: Avoid double counting in rxeof
    
    iflib_rxeof() was counting everything twice.  This was introduced when
    pfil hooks were added to the iflib receive path.  We want to count rx
    packets/bytes before the pfil hooks are executed, so remove the counter
    adjustments that are executed after.
