    lagg: update capabilites on SIOCSIFMTU
    
    Some NICs might have limited capabilities when Jumbo frames are used.
    For exampe some neta interfaces only support TX csum offload when the
    packet size is lower than a value specified in DT.
    Fix it by re-reading capabilities of children interfaces after MTU
    has been successfully changed.
