[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.
