    dev: report devargs truncation for multi-process hotplug
    
    The EAL hotplug multi-process messaging uses a fixed-size buffer
    (EAL_DEV_MP_DEV_ARGS_MAX_LEN, 128 bytes) for device arguments.
    When devargs exceeds this limit, strlcpy silently truncates the
    string. This causes secondary processes to receive incomplete
    devargs during hotplug re-add, leading to failed port
    re-initialization.
    
    For example, a MANA PCI device with 6 mac= arguments:
    
      mac=AA:BB:CC:DD:EE:01,mac=AA:BB:CC:DD:EE:02,
      mac=AA:BB:CC:DD:EE:03,mac=AA:BB:CC:DD:EE:04,
      mac=AA:BB:CC:DD:EE:05,mac=AA:BB:CC:DD:EE:06
    
    produces a 131-byte devargs string that gets silently truncated
    to 127 bytes, losing the last MAC address.
    
    Return -E2BIG from rte_dev_probe() when devargs would be truncated,
    instead of silently corrupting data. rte_dev_remove() does not need
    the same check because the length was already validated at probe time.
