udp6: don't make extra copies of iflow
udpv6_sendmsg() first initialises an on-stack 88B struct flowi6 and then
copies it into cork, which is expensive. Avoid the copy in corkless case
by initialising on-stack cork->fl directly.
The main part is a couple of lines under !corkreq check. The rest
converts fl6 variable to be a pointer.
