ipv6: remove leftover ip6 cookie initializer

Browse Source 
As of the blamed commit ipc6.dontfrag is always initialized at the
start of udpv6_sendmsg, by ipcm6_init_sk, to either 0 or 1.

Later checks against -1 are no longer needed and the branches are now
dead code.

The blamed commit had removed those branches. But I had overlooked
this one case.

UDP has both a lockless fast path and a slower path for corked
requests. This branch remained in the fast path.

Fixes: 096208592b ("ipv6: replace ipcm6_init calls with ipcm6_init_sk")
