net/ipv6: stop leaking percpu memory in fib6 info
[ Upstream commit 7abab7b9b498650404800a08765f44929fee8f31 ]
The fib6_info_alloc() function allocates percpu memory to hold per CPU
pointers to rt6_info, but this memory is never freed. Fix it.
Fixes: a64efe142f5e ("net/ipv6: introduce fib6_info struct and helpers")
