Hannes Frederic Sowa 66415cf8a1 net: initialize hashrnd in flow_dissector with net_get_random_once
We also can defer the initialization of hashrnd in flow_dissector
to its first use. Since net_get_random_once is irq safe now we don't
have to audit the call paths if one of this functions get called by an
interrupt handler.
