    net: stmmac: Terminate FPE workqueue in suspend
    
    [ Upstream commit 6b28a86d6c0bb02119f386ec2f56efde909e9bcb ]
    
    Add stmmac_fpe_stop_wq() in stmmac_suspend() to terminate FPE workqueue
    during suspend. So, in suspend mode, there will be no FPE workqueue
    available. Without this fix, new additional FPE workqueue will be created
    in every suspend->resume cycle.
