lib: Fix assert in node_parent()

With this sequence of commands in a conf file:
router bgp X
address-family ipv4
exit
address-family ipv6
exit

When the bgp AS # is currently configured as !X and the
'vtysh -b -f <conf file above>' command run, vtysh will
crash with an assert.

This commit fixes that issue.
