[IPV6] RAW: Don't release unlocked sock.
When user builds IPv6 header and send it through raw socket, kernel tries to release unlocked sock. (Kernel log shows "BUG: bad unlock balance detected" with enabled debug option.) The lock is held only for non-hdrincl sock in this function then this patch fix to do nothing about lock for hdrincl one.
