    ar8216: flush ARL table during reset after init_globals
    
    commit 33b72b8e0faf7a39faabece584fd6da61cd8f8df
    "ar8216: adjust ATU flushing in case of link changes"
    introduced portwise flushing on link down events. Now the ARL table could
    be in a chaotic state after boot where ar8xxx_sw_get_arl_table looped
    forever (depending on the entries collected while booting).
    
    Fixes FS#384.
