    ath79: fix rootfs padding for D-Link DAP-2xxx
    
    It was observed that `rootfs_data` was sometimes not correctly erased
    after performing sysupgrade, resulting in previous settings to prevail.
    
    Add call to `wrgg-pad-rootfs` in sysupgrade image recipe to ensure any
    previous jffs2 will be wiped, consistent with DAP-2610 from the ipq40xx
    target, which introduced the double-flashing procedure for these devices.
