    hotplug-sniffer: Drop "volatile" from g_once_init_enter() sentinels
    
    As documented in g_once_init_enter(): "While @location has a volatile qualifier,
    this is a historical artifact and the pointer passed to it should not be
    volatile.". And effectively this now warns with modern glibc.
    
    Drop this from our logging function.
