Merge branch 'ipv6-followup-to-fib6_info-change'

David Ahern says:

====================
net/ipv6: followup to fib6_info change

Followup to fib change for IPv6.

First 2 patches rename fib6_info struct elements to match its name,
and rename addrconf_dst_alloc to match what it returns.

Patches 3-7 refactor the code to remove the need for fib6_idev reducing
fib6_info by another 8 bytes to 200 bytes.

Patch 8 fixes the gfp flags argument to addrconf_prefix_route in a
couple of places.
