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.
