Subject: [PATCH] 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.
