route-table: Retrieving the preferred source address from Netlink.
We can use the "ip route add ... src ..." command to set the preferred
source address for each entry in the kernel FIB. OVS has a mechanism to
cache the FIB, but the preferred source address is ignored and
calculated with its own logic. This patch resolves the difference
between kernel FIB and OVS route table cache by retrieving the
RTA_PREFSRC attribute of Netlink messages.
