Subject: ospf6d: don't change SeqNum on initial DbDesc message
X-Git-Tag: frr-2.0-rc1~1628^2~14

ospf6d: don't change SeqNum on initial DbDesc message

The code was setting the DbDesc seqnum to the current seconds value of time if
this was the initial DbDesc. However, the same code was getting invoked if the
initial DbDesc was retransmitted. Caused ANVL test XX.XX to fail.
