Jiri Pirko 835d0122a5 switchdev: pass pointer to fib_info instead of copy
[ Upstream commit da4ed55165d41b1073f9a476f1c18493e9bf8c8e ]

The problem is that fib_info->nh is [0] so the struct fib_info
allocation size depends on number of nexthops. If we just copy fib_info,
we do not copy the nexthops info and driver accesses memory which is not
ours.

Given the fact that fib4 does not defer operations and therefore it does
not need copy, just pass the pointer down to drivers as it was done
before.
