ipv6: don't stop backtracking in fib6_lookup_1 if subtree does not match
[ Upstream commit 3e3be275851bc6fc90bfdcd732cd95563acd982b ]
In case a subtree did not match we currently stop backtracking and return
NULL (root table from fib_lookup). This could yield in invalid routing
table lookups when using subtrees.
Instead continue to backtrack until a valid subtree or node is found
and return this match.
Also remove unneeded NULL check.
