commit 93456b6d7753def8760b423ac6b986eb9d5a4a95

[IPV4]: Unify access to the routing tables.
the defenition of FIB_HASH_TABLE size has obtained wrong dependency:
it should depend upon CONFIG_IP_MULTIPLE_TABLES (as was in the original
code) but it was depended from CONFIG_IP_ROUTE_MULTIPATH
This patch returns the situation to the original state.
The problem was spotted by Tingwei Liu.
